However, that gray area wasn't the equivalent of dumping toxic waste into a river to build some product. The gray area was around how taxis were regulated in markets.
As a frequent Uber/Lyft/Taxi user in NYC I can say that the experience for the consumer has been fantastic. I never want to use a taxi again for many reasons.
1. There's very little recourse for lost items 2. You can't get one on-demand (now you can with apps but not before) 3. There's no recourse for having a bad driver or ensuring a good pleasant ride
So while it operated in the gray it was around archaic laws, it wasn't like it was destroying the environment.
