I don't think this works because you can have very safe failure modes - much like nuclear reactor control rods. Instead of all swerving to the right the cars would all slow down as quickly as it is safe to do so. In the second example the situation is no worse than a human driver slamming on the brakes. Sure there will be some accidents, but nowhere near the same frequency as today. Autonomous cars are much better/faster at "compensating" than humans are.
