> If instead they rarely parked we could have far fewer of them
Except that they would still spend most of their time parked. Almost nobody is driving at 3am - they will nearly all be parked every night. There are vastly more cars needed during rush hour than mid day, and then there is a smaller peak at lunch time. Most cars will still be parked 95% of the time as we don't need them that often.
> If instead they rarely parked we could have far fewer of them,
At the expense of putting even more of them on the road unoccupied going to their next pickup. Or a parking spot in a cheap area: pay less for parking is a motivation though I expect even self owned cars will do that. This is an environmental disaster - unless you have a 100% renewable power source.
> have better saturation of modern safety features into the vehicle pool (since they'd wear out at a more uniform rate), and have better incentive alignment re: maintenance
People whoes self image is wrapped up in a new car will not put up with older cars. People who want cheap will ask for older cars. As such I expect either the taxi will have different categories of costs, or more likely they will sell their used cars (with 30k miles) to someone else - if this actually develops, which again I mostly expect it won't (but it might in some areas where we will see these patterns).
> because the wastes associated with an ever growing percentage of the population owning a personal vehicle will eventually cross a tipping point.
If that is your concern you should be asking for good public transportation. In places where it is good a lot of people don't own cars. I wouldn't be surprised if you have never been to such a place (people who live in such places are rarely native English speakers, though is a common English second language for some) Still that is a much better focus on your efforts - we have the technology today, is scales much better than cars ever can, and is cheaper!
