Re: Driverless. It's the future don't you know.
There are a fair number of two-car households in the UK that could meet your "freedom" requirement with one car and a reliable driverless taxi service. There are also a fair number of households who fly to their holiday destinations and hire a car there because they prefer to have their holidays further away than a reasonable drive.
I accept the freedom argument, but I don't think it is a clincher.
