Uber has, but once you start deregulation it's just a question of time until drivers figure out they can get rides without paying Uber 20% and offer them cheaper.
And people will call them, how? The problem with the current system is that people are bullshitted to believe that any car with the right color is "safe". Eliminate this regulated and flawed "authentication" and people won't just enter some random dude's car.
You honestly don't seem to be aware of the kind of unregulated taxi service that's common in the world and that we're talking about. I think it's probably best for you to bow out of the conversation until you learn more about them.
