I recently saw some numbers, published by an automobile club, that suggested drivers over the age of 70 are involved in only 13% of crashes. My first thought was, that number is only that low because every other driver is already very cautious around old people in cars. And they usually drive rather slow. Still no reason to defend older people in death machines.

also probably they drive less, as they're likely to no longer be working for a living and so don't commute?
