I certainly didn't love their ruthless business practices, but let's not delude ourselves and admit that Uber or Lyft wouldn't exist if they didn't break the laws around taxi medallions.
Sometimes laws do more harm than good (by limiting supply and slowing innovation) and it requires creatively skirting regulations.
Things were always possible to improve the taxi industry. Smartphones had been around a few years. But it would've taken the industry 20 years to implement it correctly. In the same way that rampant music and movie piracy in the early 2000s hastened the development of iTunes and Netflix's subscription model way of doing business.
Uber shows the driver's name, their photo, and has a process for flagging drivers. Public safety is important to their business. As someone who's driven an Uber and Lyft and been through their process, I've seen it firsthand.
It's not like "medallions" worked - I remember driving in multiple taxis in pre 2010 days where the photo DID NOT MATCH UP to the driver. My high school physics teacher who grew up in Brooklyn in the late 1970s told stories about how he learned how to drive by illegally working and driving taxis around as a 15 year old.
Right now, we're just going through the same thing with AI again, and Silicon Valley is applying it's ethos of the past few decades.
There are reasons why in various industries, China is "winning the race", so to speak.
Regulations exist, but sometimes people who creatively ignore the "regulations" can win the tide of the public. It's one of America's best (and incredibly divisive) cultural capabilities.
