content: Until they ban manual driving in all forms these are going to be very complicated systems that have to watch everything. and some people will exploit them when they are driving and know how to make them yield to get the best right of way option for anything. Even if they did ban manual cars there would still be issues as the manufacturers would try to one up each other instead of working together and making one great system for all the vehicles, hell someone will exploit it to be "faster" then others by ignoring courtesies and taking the spot it can have instead of waiting its turn. But we know after VW they wouldn't think about abusing the systems out there.
