There's essentially no need to own a fully autonomous car for solely personal use. Big fleets of dispatched vehicles that you can order to show up at your door (with, this is key, low response times for on-demand service plus reliable scheduled service for your daily commute) would be a much better value proposition for most people, with superior economies of scale that you don't get with a dismal ~5% utilization that most private vehicles operate at. If such a dispatch service were done right and had a big enough variety of vehicle types and prompt enough service, it could easily supplant private car ownership for all but a relatively small group of individuals, because owning a car just wouldn't provide enough advantages to be worth the added cost and hassle.
