I assume you're being very non-US-centric since you brought up Beijing. But you're still not getting it. This isn't about martial law, which is what you're essentially describing. Even with martial law, the U.S. way too many road, way too many people, for that to be effective, but that's besides the point, so let's focus on the kill switch. Assume that self-driving cars would be not be really autonomous in the sense that you would have a very detailed local map or GPS that the government doesn't have their hands in. I think that's pretty reasonable considering what we know about government (at least the U.S. government and many other western governments). If that's a reasonable assumption say 45-50 years from now, then any individual, groups of individuals, any area (big or small), any groups of area can be kill-switched with the press of a button. That is not ANYTHING like what you are describing as possible now with "roadblocks". Don't you find that in the least bit disturbing, in that a fundamental of travel is very easily disabled for just about everybody and anybody? I love the idea of self-driving cars. Driving is a nuisance for me as well as most people out of their teens, but for people that value freedom, you have to take a realistic look at what the cost will likely be.
