We can see today that the automotive industry is receptive to regulation, even at the expense of competitive edge, when the thing being optimized for is in the name of safety. I imagine that even if there is a pattern of the sort you describe, it will be limited to the adolescence of the whole thing.

If we get sufficiently far out (decades in, after human-driven cars are completely gone, not just out of obsolescence, but due to being outlawed at least for certain areas), I'd bet that what we'd see are demands for compliance that resemble the restrictions on automakers that we have now. I imagine that the driving programs would eventually be in the hands of some regulatory agency, with municipalities being allowed some control of the parameters.
