One thing that is always questionable about Uber is their pricing. For good or for bad, in the taxi industry, in almost every jurisdiction, pricing isn't allowed to fluctuate at a whim, and it must be posted on the vehicle, and the pricing must be administered by a meter that is certified accurate on a periodic basis, and sealed afterwards.
So, as all kinds of little problems creep into view with Uber, the company itself or the jurisdictions in which it operates will simply add regulation on top of regulation, incrementally, just like the taxis, until "Uber" and "taxi" will become indistinguishable.
Many years ago, in a lot of jurisdictions, a taxi didn't have to have a specific colour, or a specific paint scheme, or any stickers, or specific signage inside or outside, either. The only thing identifying the vehicle as a taxi was the topsign, which could be removed when out of service. Eventually, between company policy and bylaws, we saw colour schemes, stickers, decals, inspection stickers, bylaw signage, and so forth incrementally added.
Had the Uber people actually observed what the industry was like in the late 1960s onwards, and how things evolved, they would realize very quickly that they're not exactly innovative, nor would they be in such a rush to pat themselves on the back for avoiding regulations. They haven't invented or created or innovated anything.
Before long, some jurisdictions will expect signage on an Uber vehicle. Someone will have an emergency and the police won't be able to identify an Uber vehicle. Or, someone will get in the wrong vehicle. Taxis look like taxis, and not like speedboats, or cube vans, or boy racer mobiles, or garbage trucks for a reason. People need to be able to identify them. Then, Uber vehicles will be wearing garish paint jobs and/or signage, too. Remember, many taxis are just a person's own private vehicle, that they use for their day to day lives. They just spend twelve hours a day "sharing" it with the public. There was resistance when those regulations and policies came to taxis, too. I remember. I was there.
Then, someone will have qwerty1234's pricing concern. And, this person won't complain on BITOG. He will raise holy heck with Uber, his municipal council, or state or provincial authority. Then, pricing will have to be displayed. And, it won't be on a smartphone or a website. It will be required on a non-removable, highly visible sticker, that the Uber person/taxi driver will hate. Again, I've been there. Then, wait until they have to buy something to administer pricing in a manner than can be inspected, as in a taxi meter. Don't forget dash cams and interior cams.
This is why I laugh at taxi drivers who are all up at arms against Uber, too. There are almost no drivers in the industry currently who were there when I started driving. I can count all of them in the city on one hand. For people in the business from when I started at the periphery, before I drove, when these changes started, even fewer are left. The current drivers don't know what the taxi industry went through, and don't understand what faces Uber. Uber invented nothing. They innovated nothing.
They didn't invent a practical wristwatch smartphone. They didn't invent a quantum computer. They didn't make chemical rocketry obsolete. They didn't relegate the ICE to the dustbin of history. They just reinvented the taxi. To make matters worse, they actually turned back the clock on themselves. They get to experience all the pains of new regulatory regimes, already completed by regular taxis, all in time to watch the driverless car render them both obsolete simultaneously.
Uber is as innovative as would be Ford avoiding CAFE by selling horses.
