[Stumped]

May I attempt to put things into some sort of perspective as I feel very strongly that too much speculation can only serve to aggravate what is becoming a very diverse debate. I finished my police career as a Traffic Patrol Sergeant with a hard earned 1st Class Advanced Driving qualification which required a much higher standard of knowledge and ability to acquire than the civilian version. Over the years I and my colleagues visited, supervised and investigated countless accident scenes ranging from minor damages, through to serious injuries and fatalities, in all weathers and on road categories ranging from country lanes to trunk roads and motorways. I can honestly state that the number of blameworthy accidents I attended that were attributed to elderly drivers was but a fraction of those caused by young, inexperienced and reckless drivers whose engine power far exceeded their mental ability to cope with the responsibilities that the holding of a licence to drive demands.

I rest my case.
