I'd say the big barrier to more cars is cost, not being unable to drive (particularly in big cities).
Think of how much an average car is used in relation to it's value ie £/hour.
Now think about the changes in how we own and use things nowadays.
Driverless cars would go hand in hand with an Spotify-Uber-style system. If cars were utilized to even 50% of their ability then the cost would plummet to an almost meaningless level.
When I was talking about more cars I meant in absolute numbers. It may be that the number of journeys increases but I think the number of cars doing those journeys will drop.
