I'll post an analogy for when I'm flying. If I arrive at the destination in one piece, still alive, all the other stuff like lost baggage, smelly co-passengers and turbulent weather fade to black. You got to your destination with minimal drama, in one piece. From what one reads occasionally about these services, things can get a lot more discomforting than your ride. Also, that was a heck of a lot of money for such a short trip - what would have a plain ‘ol yellow taxi cost? Every one of those I've been in were in pretty good shape and the driver had his credentials prominently placed.
Not dissing you at all, rather, thanks for posting your experience, it gives one more reason not to use these services, I'll call a taxi instead.
