Don't agree at all, I was a better driver at 25 than I am now twice that age, reactions were much sharper, eye sight better, and in better physical shape.
I would rather be sat at the side of a young driver than a doddery old one, whilst young drivers have their share of accidents the young male driver accident rate is falling, unfortunately the young female accident rate is rising. Elderly driver accident rates are not only rising but increasing in seriousness as well, all alarming statistics.
IMHO there's no place on UK roads for driver over 70 and thats the age when I will hang up my keys as I know I will not be good enough to cope with modern traffic by then, trouble is some of our elders will just not admit it's time to give up and would rather go on and cause a fatality then lose their independence, I think there are a couple of words for that selfish and stupid
