I should also point out that my mother, who's almost 70, almost lost her life to a driver who had recently turned 17 and just passed her test.
While there may be an issue with older drivers, there are also issues with drivers under 70.
It may be that someone over 70 might not be as sound a driver as they used to be, but I have seen a growing trend among younger drivers to treat other road users with contempt.
The other day, a van coming the other way almost took my door mirror off, while my vehicle was almost stationary and on the verge, yet he insisted that I had tried to force him off the road. Thankfully, my dashcam proved otherwise, but it was his attitude and violent demeanour that caused a clash of personalities, and his blatant refusal to take responsibility for his rash action that could have caused a serious accident.
You only have to travel to a supermarket car park after dark to see evidence of youngsters pratting about in their cars.
I will also point out that while this elderly person may have caused the crash, plenty of elderly people can still drive in a reasonable and safe fashion, albeit a little bit slower than most of us would prefer.
I wonder how many here would consider themselves too old when they reach 70? I will wait until I am seventy, in twenty years time, to decide if I am still able to cut the mustard.
