Think you may have misread my post - that was exactly my point. Driverless cars as a lease-only thing will have much slower take-up than driverless cars with private ownership. If the only business model is lease, then there will be slow takeup, IMHO. At the moment most people are very much used to cars as a personal, private space. I also think there will be supply & demand problems (certainly outside of large urban areas) - people will have to adjust to paying different prices for different times of day (just look at the fuss that there's been over Uber's differential pricing model for an example of 'luddite' reaction).
I agree with you that long term it's a more efficient business model - I just think it's going to take a long time to get everyone thinking in the same way.
Sorry if I misunderstand. Yes, that's exactly the point I was making that the business model will take a lot of time working and there will be changes to society too - for example, managing rush hour prices will be controlled by different prices, as you point out, this will be a lot easier.
But the advantages are huge: fewer delays, fewer accidents, more disposal income, more relaxed travelling and so on. The far bigger problem is what to do with the unemployment of taxi, lorry and van drivers - that would be a massive upheaval.
