My point would be the part about background checks that you snipped out so that you wouldn't have to answer it.
Answer it? You didn't ask a question. The point of my link was to show that background checks for regular taxis are not sufficient to have a 100% success rate of weeding out potential sex offenders. Why should that be any different for Uber? (note, that was a question for you) People like to point to stories of sexual assault surrounding Uber as a reason not to use them, when the fact is that sexual assaults happen in regular taxis also. I don't think that Uber made any claim that their service is 100% sexual assault free, but frankly I think it is safer than a taxi. I sent a friend home in an Uber car the other night after some drinking at around 3:30 am. I ordered the car, so I was able to track where it was going on my phone and I verified that it took her straight home (I also entered her address so he knew where to go without asking her). I don't have that same capability with a taxi. If I wanted a further assurance I could have called her and talked to her all the way home. I also have the driver's name, vehicle make and model, and license plate number because Uber tells me all of that information. If I call a cab and she gets in it and she doesn't let me know when she's home, what are my options? (there's another question) Call the police and tell them who I called, and then they can call the cab company and work out with the dispatcher who got the call, then try to locate them over the radio and hope they respond? How long does that take? What else is happening in that car while all of that is going on? How is that any safer than letting me know where the vehicle is, who is driving it, and having a description of his car including location?
Like, say, while driving for an illegal limousine service without commercial insurance (and driving without insurance is a criminal offense in California).
Why is it that Uber can operate in California, then? You make it sound 100% illegal, so why do they advertise California cities among the places they operate?
