> A lot of people I talk to imagine that the tech problems have all been solved and all that’s left is getting legal and public acceptance. There is great progress being made, but nobody should expect these cars to be perfect today. That’s why they run with safety drivers, and did even before the law demanded it. This time the safety driver also decided the bus would yield and so let the car try its merge. But expect more of this as time goes forward.

I think most people who say the issues are social and legal don't think the technical problems are solved, they just think that we are inexorably progressing towards solving them at a more rapid rate than the social and legal problems.
