Re: Missing the point.
"Once driverless cars are a reality, the need to own a vehicle will start to reduce."
Has taxis existing reduced the need to own a car? Not much: Way, way too expensive per mile.
Driverless car is a taxi, only even more expensive, so it is not an alternative to your own car. Not for a long time.
And not so much 'public transport' either when it's comparable to private jet in price.
