Was it That Long Ago?

Exactly 44 years ago today, I passed my driving test.

I was seventeen, and was being taught to drive by my Father. This was for two reasons. Firstly, in order to wean me off motorcycles, he offered to do it for free, and secondly, I had bought a car in which to learn. 

My first car was a twelve-year-old Morris 1100 saloon. It was, in many respects, a great car to learn to drive in.

Not my car – but the same model and colour

It was a simple machine, with no clever safety systems – apart from old fashioned lift latch buckle seat belts.

It didn’t even have any real “comfort” systems if you exclude the two-speed fan assisted heater.

Its front wheel drive made it easy to drive round the country lanes of Sussex where I grew up. 

The Morris 1100 was quite revolutionary when it rolled off the production line in 1965. It used the new space-saving BMC-designed Hydrolastic suspension system. 

To put it simply, this system replaced the springs and shock absorbers used in conventional cars with rubber bladders known as displacer units at each wheel.

The front and rear bladders on each side of the car were connected together with pipes and valves. When the front wheel encountered a bump in the road, it would force fluid from the front bladder to the rear bladder, which minimised the pitching of the car over bumpy roads.

It also had a brilliant side effect for a learner. It made hill starts really simple.

On a hill, with the parking brake applied, all one had to do was engage first gear, cover the brake pedal, and let the clutch up slowly. The vehicle would then gently rise up on the rear suspension. As soon as this happened, the handbrake could be removed without the car rolling backwards.

I must say it helped me considerably!

So, back to the point. 

I had applied for my provisional driving licence and got it back in time for my 17th birthday. I had to buy my very first driving insurance policy out of my meagre apprentice pay, so it was a third party only policy. 

The good old paper driving licence, showing provisional driving entitlements. Not mine though!

I guess this was a bit of a calculated risk. I assumed that it was a little unlikely to spontaneously combust, and any self-respecting car thief would be horrified to steal such a shabby looking car – especially one that had a slightly Miss Marple image.

For my first lesson, it was decided that we would leave the house very early to avoid traffic as much as possible. We agreed that we would use quiet country roads to start with and then progress to busier streets and towns. 

I jumped in the passenger seat, and we drove sedately to the south west edge of the town, heading for the village of Turners Hill. 

Dad pulled over onto a layby at the right, and we swapped seats. 

After 44 years, the lay-by is still the same…

Crunching the gears, I kangarooed off on the start of my driving adventures – and all without the aid of dual controls!

An hour of driving up to the village, turning around, and driving back to the layby resulted in me being able to change up and down the gearbox, and smoothly pull away.

So, it continued. Practicing reversing into a parking bay on the Imberhorne industrial estate, reversing around a corner, and three-point turns. Hill starts without the car rolling backwards and crushing the matchbox that my father had placed behind the rear wheel.

Eventually, after a few months, Dad pronounced me ready for test, and so I applied. Crawley was the closest test centre, so in preparation I regularly drove the family over to Crawley for Saturday shopping, and was reasonably familiar with the place.

I eventually got my test date, which was the 2nd of February 1977. This was a Wednesday, and Dad couldn’t get leave to get me to the test centre.

Luckily, one of my Air Cadet friends who had passed his test the previous summer offered to take me.

My test was as simple as my car.

Upon arrival, I reported to the receptionist, and she asked me to take a seat. In due course, I met my examiner; he looked a little like Sherlock Holmes, complete with a deerstalker hat.

Having checked my provisional driving licence and my insurance documents, he asked me to read a nearby car number plate, which I did with ease. Not sure I could do it today without my varifocals!

Without further conversation, we got into my car, and I drove around Crawley, following his directions. 

The emergency stop was for real, rather than him banging on the dashboard in accordance with his briefing.  I was “making good progress” and driving at just under the posted 30 MPH limit, when a car suddenly pulled out of a side junction.

I slammed the brakes on, and the car rapidly came to a stop, without me locking any of the wheels up and skidding on the cold damp tarmac.

The deceleration forces were impressive. His clipboard shot into the footwell, and he pitched forwards. “Oh god” I thought, please don’t let the examiner break his nose on my car”

Luckily, he didn’t. Leaning back into his seat, he turned and smiled at me. “That was very good. I shan’t be asking you to do a further emergency stop.”

Having completed all the required test items, we drove back to the test centre, and he fished a folder out of his battered briefcase.

Flipping through the folder, he randomly selected road signs and marking and asked me what they represented.

I obviously answered correctly, as he ponderously got out of the car and trudged back to the warmth of the test centre.

He gravely started filling out a document. Was it a failure or pass certificate? 

“Well done Mr. Charlwood. You have passed. Congratulations!”

So – I was one of the 40% of test applicants that passed their test first time!

I thanked him, and went to see Andy who was waiting patiently. “Well?” he enquired. “Am I driving back, or are you?”

“I am” I said proudly. We went to the car park, and ceremoniously ripped the L plates from my car, and I nonchalantly tossed them onto the back seat for disposal later.

We then drove to Brighton and back on the busy A23. 

Just because we could!

However, things are very different now. 

The driving test has metamorphosed into something much more complex. Hill starts and reversing round corners have been removed from the test, and navigating whilst driving using a GPS Satellite Navigation system has been included. 

The almost casual theory questions used by my examiner in his ring binder are gone – replaced by a formal theory test, which is computer based. 

The theory test also includes a hazard perception test, using 14 short video clips to establish whether the candidate has good recognition of developing hazards and risk assessment skills.

Bizarrely, (in my opinion) candidates may use vehicles that have hill start assistance systems.

In my world of professional aviation, skills tests are conducted using the equipment fitted to the aircraft, but candidates still have to demonstrate navigating or performing the required manoeuvres with the enhanced systems shut down, thus demonstrating that they can control their aircraft in all situations.

Having said that, my car is fitted with a hill start assist system and there is no means of disconnecting it. I guess thats the same in most current cars. Unless you know better?

I must add, somewhat smugly, that it never activates, because I was taught how to do a hill start using blended clutch and brake control.

The driving syllabus and the test upon which it is based unfortunately lags considerably behind the rapid development of Autonomous Driver Assistance Systems (ADAS).

To illustrate this, new drivers are not currently required to be taught the use of cruise control, or to recognise its limitations, and how to use it safely.

So, where do YOU place your feet when the cruise control is active and engaged?

I keep my foot over the accelerator. Some people I have driven with place both feet onto the floor.

I find this a little startling. 

Simple risk assessment shows that it is possible to lose spatial awareness of where the pedals are in relation to the drivers’ feet. In an emergency, do you really, instinctively, know where the brake pedal is?

New vehicles are loaded with ADAS, and whilst many younger drivers may not be able to afford new cars, they should still be aware of the types of systems available. New drivers may be renting cars to which these devices are fitted, or be given a company car which has many safety systems fitted as standard.

Statistics show clearly that the highest risk groups for accidents are very young drivers (17-21), and the elderly (80+) both of whom may not have sufficiently developed judgement to ensure their safety. 

Both groups are unlikely to be driving the latest cars which have the additional safety systems.

So maybe those that need a good understanding of ADAS and would benefit from the additional safety, are the drivers most unlikely to have a car fitted with it.

At some point the driving syllabus and the test will address these issues.

Until that time, all I can say is…

Drive defensively and learn as much as you can about the systems that YOUR car is fitted with.

Go well, and be safe!

Autonomous Vehicle Safety Devices – Do you turn YOURS off?

If you drive a fairly recent car, it will, in all probability, have a number of added features to make driving not only a more enjoyable experience, but also a safer one.

When I started driving in the mid-1970s, driver safety systems – apart from the most basic, were virtually non-existent.

I started my driving career at the age of 16 with a 1965 Austin 1100.

Same colour, same condition – different registration! This is a 1966 model

Minimal controls, no radio to distract, and hydrolastic suspension, which for those of you that are not familiar with it, made performing hill starts a simple manoeuvre.

A four-speed gearbox, and a disproportionately large steering wheel by todays standards. (This was to compensate for the lack of any sort of power assisted steering).  

My parents believed this to be an ideal car for a learner.

But was it?

It had absolutely no safety features. Not even a collapsible steering column! In vehicles without such a device, in a frontal crash, the impact and subsequent deformation of the body shell and chassis could drive the steering column backward, in many cases impaling the driver to the seat.

Austin/Morris 1100. Simple, uncluttered, yet maybe deadly!

Interestingly, a patent was filed for a collapsible steering column way back in 1934, but it wasn’t until 1959 that Mercedes Benz fitted them to its MB W111 Fintail. We had to wait until 1968 before Ford fitted them as a standard item to all new cars.

My car did have one quite advanced feature – it was fitted with disc brakes on the front wheels, and drum brakes on the rear wheels, making it almost unique for a small, mass-produced car in the early sixties.

Let’s move on to crumple zones. My little car was built quite simply, and any energy created in a crash impact would be transmitted throughout the whole car until it dissipated. Modern cars are now designed with front and rear panels that deform in a controlled manner, spreading the loads and therefore dissipating the energy to survivable levels before it reaches the occupants.

Volvo introduced longitudinal steel bars to protect the occupants from side impacts, a system that Volvo imaginatively called SIPS, Side Impact Protection System. That was back in the early 1990s, and now all modern cars are built with a rigid passenger safety cell which, amongst other things, prevents the engine from being forced into the passenger compartment.

Losing control of a vehicle causes many accidents. The moment that wheels lock up under heavy braking, is the moment that the driver effectively becomes a passenger, and the skidding car has an uncontrollable trajectory, potentially leading to an impact.

The aviation industry has been using anti-lock brakes since the 1950s when Dunlop invented the Maxaret system, which was fitted to various aircraft types. By preventing the wheels locking up, aircraft landing distances could be reduced by up to 30%, and the use of the system extended the life of tyres considerably.

Vehicle engineers weren’t slow to recognise the opportunity to enhance car safety, and in 1966, the Jensen FF Interceptor became the first production car to be fitted with mechanical anti-lock brakes.

Modern systems are fully electronic, and are so sophisticated that they can work in conjunction with electronic stability systems to reduce brake pressure on one wheel, or even redistribute the brake effort from front to rear, or even side to side to ensure that the driver remains in control.

Other safety features are less glitzy, including the humble padded dashboard and flexible sun visors, to head restraints and laminated windscreens, but I am sure they have all made a positive contribution to reducing post-impact injuries.

Air Bags and Air Curtains, Seat belt pre-tensioners (to tighten the lap-strap within milliseconds of an impact being detected) and tyre pressure monitoring systems play a more active role in saving lives.

Safety device development continues at high rate.

Due to the ever-increasing sophistication of vehicle on-board computer systems, and better understanding of accident causal factors, there are a now a complete suite of Advanced Driver Assistance Systems (ADAS) that are being fitted into new cars.

Lane Departure Systems that monitor the vehicles distance from lane markings warn the driver (and in some models will intervene to bring the car back into its own lane) of a deviation from the chosen lane.

Blind Spot Monitoring uses a system of sensors and cameras to detect vehicles in adjacent lanes and activates a warning – either in the external door mirrors or within the driver’s area of vision. Some of these monitors will also activate when the car is placed into reverse gear, and will warn of approaching vehicles or pedestrians. This enables cars to be safely reversed out of car parking spaces.

Active Cruise Control (ACC) may be set up to automatically maintain a certain speed and distance from vehicles in front. and will automatically decelerate the car if the car in front slows down. If the spacing limit is breached, then the system will communicate with the braking system to apply the brakes. Drivers will also be warned by an audible alarm and a visual prompt to intervene and apply the brakes.

Driver Monitoring Systems can measure the level of arousal and alertness of the driver, using eye tracking technology, and driver steering inputs. If the driver begins to exhibit symptoms of drowsiness or incapacitation, the system will activate, generating a loud audible warning, and in some cases the seat or steering wheel may vibrate.

Should the driver not react to an obstacle under these circumstances, the car systems will intervene and take avoiding action.

Many accidents occur due to breaches of the speed limit, so ADAS provides another system – Intelligent Speed Adaption to assist in preventing a driver from exceeding speed limits.

These systems may either be active or passive in nature; passive ISA will simply warn of an exceedance, whilst active ISA will either exert a deceleration force against the accelerator pedal, or will reduce engine power and apply the brakes.

My current car was manufactured in 2017. It has standard cruise control, electronic stability control, ABS and is littered with airbags.

My only additional Driver Safety Systems are manually optimised…

I use the mark one eyeball and good driving practices that were ingrained in me during my driver training. Mirror Signal Manoeuvre when changing lanes or joining a motorway. A good habit picked up from being a motorcyclist – I actually turn my head and look over my shoulder when lane changing.

Despite all of these advanced safety systems being available, many people are ignorant of the systems fitted to their cars.

In part, this is due to sales staff at dealerships being either unwilling, or unable to explain satisfactorily how the systems work, the advantages and practical use of the systems, and the limitations of the systems when in everyday use.

Secondly, having checked the Driver Standards and Vehicle Agency website, and reviewed the UK Driving Test Syllabus, there appears to be nothing in the course to ensure that drivers have an understanding of integrated safety systems.

Unless Approved Driving Instructors teach the practicalities of Advanced Driving Assistance Systems, and their limitations, drivers will remain in ignorance of the benefits that these devices offer.

According to a recent survey conducted by Autoglass, 41% of drivers with ADAS equipped vehicles intentionally disabled safety devices such as Autonomous Emergency Braking and Lane Departure devices!

The survey further revealed that 24% of those drivers responded that they were not provided with any information about the importance of these features and how they work when they had the vehicle handed over to them.

55% were unaware that these safety-critical systems need to be re-claibrated following a replacement of windscreens of repair of panel damage.

67% stated that they believed that more education and training is needed before driving ADAS-equipped cars.

The best safety device in every vehicle is a well trained driver. A well trained driver would not disable safety systems designed to save lives.

Maybe its time to start the training?
