I very much agree with TTT. If fit and able to lean to ride a motorcyle it would be most advantageous in later driving abilities. Once you have ridden a motorcycle you are quickly aware how vulnerable a motorcyclist and pedal cyclists are to other road users. This should,hopefully, make a 4 wheeled driver more aware of other vehicles. I accept not all are able to ride a motorcycle for various reasons. I have taken about twenty driving tests in my driving life,not because of failure but for advancement on both cars,motorcycles,HGVs and PSVs plus other specialist driving techniques. I don't think the standard of driving we now see on our roads can get much worse.
I took my son out for a drive for a check test prior to his driving exam. His instructor said he was ready for the test. He was not and failed twice before obtaining a full licence.
I asked him to show me a 3 point turn. He had never done one and didn't know what I meant. Ditto reversing around a corner keeping close and parallel to the kerb,ditto a hill start. He had no idea of speed awareness braking distances etc etc. He had never heard of the Highway Code and when I explained what it was he told me his instructor advised him to look up on the web and read the sample questions given for the theory test.
I am all for Graduated Driving Licences and at nearly 70 I welcome the requirement ,if it becomes law, to take any further testing deemed necessary.
Having passed an Advanced Driving Course at about 29 years of age having taken several progressive courses from basic I was told that statistically I would be likely to be involved in a RTC within a month.
I was fortunate. It took a while longer than that.
For a 20 year old to say they have not had a RTC then I will say .Good for you but there is plenty of time,hopefully,left for you. So don't get complacent.
