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.
Whether this is one of those "we accept some number of school shootings cause gun freedoms are just so great" issues or not is I guess its own matter for debate. But the fact that this happens, and then as dudes we get to discuss it at arms length on the internet and opine about whether "99% of trips completed without incident" is reason to dismiss it all out of hand may help explain why an individual woman getting home from the bar might choose to walk or take waymo vs getting in a cab and risk joining the unlucky 1%.
