Network effects. Car manufacturers will still want a place where they can find many riders so that they can maximize utilization (and thus, profit), while riders will want a place where they can find many available cars (so they don't have to wait). There's going to be some platform that connects riders with self-driving transportation, the only questions are whose, how many, and how much value they extract out of being the platform.
