Well, besides that I'd never get in a Uber, nevermind if anyone in one would ever have a mind to hit on me in one... I also know that insisting that I have a dick (which is what cis women mean when they say they're men in response to a guy making them uncomfortable and being intrusive, yes? That they have a penis and the man hitting on them should or will be appalled and disgusted with them, and himself, and simply shut up and leave them be, now that they've made this declaration?) isn't a good way out of a rude or uncomfortable situation. Actually, it can in fact make uncomfortable, intrusive situations worse, and unsafe in a way they wouldn't have been otherwise. And I also know it's not a good joke. So no I wouldn't.
