Re: a choice
I rather think that's Mr. Brin's point.
Driverless cars are the solution to so many problems, from bad drivers to congestion via drivers on drugs, that once the technical problems are cracked the incentives are very strong. During my career I have had the misfortune to travel with so many people who should not even be allowed out in control of a skateboard - all of whom considered themselves to be excellent drivers - that I'm cheering on Mr. Brin every millimetre of the way.
