Yes that's fair enough, but I see far more "experienced" drivers making downright stupid mistakes, speeding, and generally thinking they "own" the road then I do younger drivers.
Unfortunatly, younger drivers have a bad reputation due to the fact that there is a small minority of hooligan's, who are generally classed as "boy racer's" who do stupid things and write off car's, cause and get involved in accident's etc...
But in all honesty, in my own experience, the older driver's seem a lot worse then younger drivers, sometime's its probably because they are not up to date with the rule's of the road, sometimes it's due to complacency, sometimes it's due to them simply not giving a damn about anyone else on the road because they have been driving X amount of year's and think that entitle's them to freedom on the roads, and last but not least, sometimes it's due to them simply taking speed for granted, thinking that because they have been driving for x amount of years, it means they can drive at 100mph safely.
There isnt many drivers on the road who have had any form of race specification training, yet there are ton's of drivers who cant help but drive everywhere as if they are on a race track.
As I say, personally I find 25+ males the biggest problem on the road when it come's to speeding, and women in general the biggest problem when it comes to general driving ability. The biggest problem in terms of stupidity is admittadly the 17 - 21 age range, mainly male's, but they don't generally have the car's to be driving at stupid speed's and tend to understand the roads better then one might think!
