Thank you.
That's a very good question. I would state first that typical assistive devices tend to be for people who have serious physical disabilities. On the other hand, most people have some kind of chronic disease, and as people age, most of us will be labelled with some chronic disease or another, and people do continue to drive.
What's really quite fantastic about older drivers is they tend to self-regulate. They will adjust their driving. They will not drive in all the more difficult circumstances. They don't tend to drive in rush hour, at night, or in bad weather. So they really adjust their driving, and, again, they drive less, and that's why, overall as a group, the number of crashes they're involved in is not greater than any other group—actually it's less than any other age group.
Canadians should not be worried about older drivers as a group. There are some drivers we have to look at, and we have to continue looking at ways to identify who needs more assistance, who may need help to drive or maybe transition to non-driving status. But I think as a society we shouldn't be worried about them.
