Some people have pointed to the very low rate of accidents in elderly drivers as an argument for them keeping their drivers licence, however a recent study by University of Alberta shows that, when measured as a ratio to number of kilometers driven, the rate of accidents rises steadily from 70. By the age of 75 elderly drivers accident rates are exceeeding those of 16-24 year old age group.

Combine this with increasing frailty and reduced ability to recover from road trauma and we have a situation where the benefits of continued mobility are outweighed by the risks that driving involve.
