Explain to me why having an actual physical meter and seat sensors are sensible regulation? To me, they are clearly barriers to entry that make it harder for individuals to participate in the sell side of this market. Neither are necessary to provide the service in a safe and trustworthy manner. They simply make it so people need to actually acquire special cars with the seat sensors and then go through additional bureaucratic hoops to get a physical meter installed. This is so obviously protectionism and anti-consumer, that I don't see how anyone can consider them sensible except the taxi cartel.
