To do that you have to first recognize that current city designs are 100% for car manufacturers, not people. To take away the olds licenses is to restrict them in their homes, like people under already are. It's freedom they're after.

Change the culture around freedom of movement, and I guarantee the olds will give up their keys before they're even old.

"Olds are some of the worst drivers on the road"

A bold claim, let's see if accident statistics back it.

"Drivers 65 to 74 account for 13.6% of licensed drivers, but represent only 7.6% of drivers in all crashes"

"Sixteen- to 19-year-olds represent 3.8% of licensed drivers, but account for 8.8% of drivers in all crashes"

Nope, guess not.
