As a man, I never understood how bad this was. I have only felt unsafe in an Uber a few times, mostly because the driver should have had their license revoked due to their advanced age.
Without going into too much detail, I’ve learned just how bad it is. On the “less” vile end of things, my current parter had some desperate slime try to offer her money for sex. I made sure he reported him, but Silicon Valley loves to enable sex criminals, I imagine he’s still out there.
