You're right, but I think that most people who would like a robocar place the most value on doing something else while en route. Even if it took longer (which, I agree, it would (unless the traffic was all robocars, which I can imagine actually being more efficient in many traffic scenarios, despite their slavish adherence to regulations)) I still think that most people would be happier doing something important or interesting for 35 minutes than they would be getting there in 27 minutes that they weren't able to use because they had to drive.
