Taxi regulations typically limit supply (raising costs for consumers), protect drivers over passengers (in Vegas a complaint against drivers must be notarized), and protect favored ethnic groups (c.f. Shiv Sena's taxi law in Maharashtra). Can you name any contemporary real life problem that taxi regulators solve better than Uber's own regulators?
I'm aware that historically, taxi regulation purports to solve real problems. But I claim that in the modern economy, Uber has solved every single one of those problems better than regulators can.
Of all the cities I'm familiar with (NYC, Vegas, Chicago, Mumbai, Delhi, Pune, Bangalore, Kuala Lumpur), I can't think of a single instance where a regulated taxi gave me better consumer protections than Uber/Lift/Ola.
So again, the simple question: what problems that currently exist would regulation solve?
