Seconding that. I took a half-dozen Uber rides in Las Vegas two weekends ago. My biggest concern was trying to figure out how to use the app to tip them. All drivers were cordial, polite, had no problem with routing (admittedly, it's pretty simple in Vegas). One driver was a smoker and the car smelled and that was the only negative in 6 rides. Overall, it's the end-to-end experience. Call up the app, type in a destination, head to the curb. The car shows up about the same time I get there, I hop in, chat a bit on the way, hop out at the destination, rate & tip via the app and go on my way. The seamless experience, so far, makes up for the (so far mild) idiosyncrasies of drivers and cars.
