Absolutely. It's a huge cliff. Old people eventually can't drive, and in car centric places, immediately lose all independence. we're going through it right now in my family. Keep your ears open and you hear it all the time; "grandpa drove into a parked car, not sure if he should still be driving".

I plan to retire (finances willing) in a walkable city, for just that reason.

Same argument at the other end of age spectrum. American children have no independence, only because cities are dangerous because of cars.
