They're almost at parity now though, at the normal person level in Chicago at least. I get nearly killed by either on my bike just as easily :)
Glad I'm not the only one who notices these cars randomly driving slowly or parked in the bike lanes waiting for the next ride to come in.
Ride safe..
I've seen drivers parked in lots when they are awaiting a request but in places where parking is charged such as downtown, I think they prefer to keep looping around blocks.
There may be an interesting case study to be made on the environmental impact of these idling cars.
I also had one reckless idiot spend the whole ride texting while driving, too.
