I don't feel good about it at all, and that's based on experience with two elderly relatives who struggled to stay in their own homes after it happened. But by the time they were that disabled, walking was much more of an issue than driving. They couldn't walk around the store once they'd driven there, so living in an apartment next door to the store wouldn't have solved the problem.
When DH and I moved to this city five years ago we searched hard for a suitable house in a safe, quiet neighborhood that was within walking distance of a neighborhood market, drug store, a few restaurants, etc. But unlike you, to us the walking distance criterion was not so important that we were willing to sacrifice most of the other things we wanted. The suitable house simply wasn't there, at least not at that time.
I've now seen your many posts saying that everyone "should" move close to public transit. I hate to be the one who breaks this to you, but if all the people with no practical, reasonable access to transit tried to move within comfortable walking distance of it, huge parts of the US would be depopulated and people would be living 50 to a room.
There's certainly a problem, but at this point the solution doesn't really lie on a level where individual action's going to do any good.
