The problem with regulation isn't Uber. It's the extraordinary costs required to operate a taxi - mostly the $200k plate. If I can get a background check and a card certifying me to be allowed to work with children for about $50, why does it cost nearly $200k to get a taxi license. Require licenses, reduce the costs to improve competition, and let the various companies compete on service.
And yet in New Zealand, Uber is instructing its drivers to ignore the legal requirements for commercial passenger transport, which boil down to a background check, a license endorsement, and a more frequent warrent of fitness check. Uber is opposed in principle to even the most minimal safety legislation.
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?
