It is frustrating that you ignore the meat of what I wrote, pick on a couple of things you can object to, and carry on carping. I'll try one more reply and see how it goes.

Your imagination is poor. I've lived on 4 continents and am on an extended trip even as I write this.
We're talking about different kinds of regulation. You apparently care about things being shiny; most regulation, though, is about setting a minimum bar.
In the early, high-growth days of something, regulation is rarely useful because everybody's on their best behavior. It becomes more important when things settle down into a relatively steady state. Then, the incentive to shave nickels and dimes can come out elsewhere. E.g., taxis face significant safety inspections and maintenance requirements because when you use a car as a commercial vehicle, you put a lot more miles on it and you are more likely face safety issues.
We don't yet see these problems with UberX because it has only been going for a few years, and because Uber has a strong incentive to keep from becoming an obvious disaster until growth slows and revenue gains come more from exploiting their market position.

Gosh, might they have some incentive to only say happy things to you? Gosh, might there be some selection bias in your sample? Gosh, might people not talk about their pain and fears to random strangers?
