Al Neuharth isn't wrong, but he's a rich guy who doesn't really ever have to drive if he doesn't want to. With an aging population, the elderly driver issue will increasingly be an issue, but what's the solution? So many people live in places where there just aren't other options, aside from paratransit services. And those are expensive to provide.
I really don't know what the solution is. As the suburban population ages this is increasingly going to become an issue. Mobility issues aren't the same for all elderly people. Some can walk, but shouldn't drive. Some can happily ride the bus, some have mobility issues that might prevent even that. But lots of people live in areas where driving is the only option, and taxis aren't part of the driving options.
