Car safety and work hours; yes. But it's not clear to me that other types of regulation are desirable. Environmental standards should be the same for all cars; driver training has been made almost redundant by sat-nav systems; a reputation-based system might be better than a 'requiring pickup' system. In particular, I want a regulatory system that makes it easy for someone to be a taxi driver only from midnight to 2am on Saturday nights. Or only to and from the airport between 3pm and 6pm. This is the sort of flexibility that brings down costs overall.
