Having driven well over half a million miles on U.K. roads over the past 40 plus years , I think that young drivers get a bad reputation that is often not deserved. Yes, you get the boy racer types who drive like idiots (and ramp up the statistics), but if anything most are quite cautious and very sensible as they are paranoid about having to re-take their test or being unable to afford insurance in the event of a claim or endorsements. Also, very few youngsters drink and drive in comparison to their parents or grandparents generations (drug driving is sadly a different issue).
After many years of studying who is behind the wheel of cars being driven badly, I have come to the conclusion that the worst offenders are elderly drivers, some HGV drivers (drifting into the hard shoulder whilst distracted – see that every week without fail) plus (and I shall put this diplomatically) those who may not have passed their driving test in the U.K. many of which are worryingly taxi drivers!
