I guess? I was on a date with someone and we took an uber back to her place after a concert, and she mentioned off-hand afterward that had I not been there she would have just walked... even though it would have been over an hour on foot, it just wasn't worth the risk after multiple bad/creepy experiences taking carshares home late at night.
Maybe it's a bit like cops: they're not all bad, but the system is kind of set up so that bad ones thrive and good ones burn out. It's going to be a particularly kind of person who is willing to spend their late Friday night driving drunk people home from the club, and honestly if you're a vulnerable person, maybe the guy most willing to do that job is the one you least want as your particular driver.
Fair. There is no reason to not believe you. Women are more vulnerable than men. Still, calling the service dangerous without any backing, by some report in addition to annecdata, is offensive, and only does a service to the provider, however well meaning the deduction may be.
