Let me give you an example: I took a taxii from the airport to my home, the guy took the route I knew was very long and with only 20% of the trip I was being charged like $100 and asked him to immediately stop at the next parking lot he sees. Took my luggage out and called Uber that completed the rest of the trip for $50. Not my first time dealing with scammy taxi drivers either. It was a nightmare calling a taxi before uber, it will take them at leasr 45min to get a guy and good luck getting them to wait on you and coordinate your pickup.
My point is, it may be operated badly but it provides a ton of value and has the advantage od being first to market. I have always wanted to try Lyft for example but I never had to, never been in a situation where I needed them (except for scooter rentals in santa monica once -- didn't work at all). I avoided Uber eats on purpose but the rest were so crappy I switched, much more costly but I have a lot less problems now and they even added grocery delivery now. They are quite possibly one of the most valuable companies at he level of Walmart, whether or not they can realize that value globally and get the timing right I have no idea, but I am rooting for them.
