Those things are easy to detect. It's much less easy to prevent a simple lane change. Some cities have "bus only" lanes, which cars use anyway, but it's easy to detect them since they don't look like busses. How are you going to detect that my car isn't autonomous?
These are pointless concerns. It is a technically trivial problem. We are literally in a thread about self driving cars. If there is a will to enforce it then it will be enforced.
That's what I'm trying to get at--why would there be any will? Why should we all decide to give up a lane to people who are rich (or stupid) enough to buy a brand new car?
