What about car sharing schemes such as Car2Go, Zipcar, etc, where you pay just for the amount of time you use the car? Unlike autonomous cars, these are available now and proven to be successful. Here in Rome Car2Go have over 600 cars, so you are usually no more than 5 minutes walk from one. You can also leave it anywhere in the 'home zone', rather than having to find a specific car sharing parking space. There is also another service run by the city that has a similar number of cars. The prices are quite high, but if you just need it for odd trips (i.e. not commuting every day) it's still going to be cheaper than owning a car, and a lot easier than having to deal with public transport.
