I'm seriously impressed by how calm this woman is considering the dude just outright admitted that he would've kidnapped her if they weren't in Canada. Fucking hell.
This is actually a really common response to a threat. There's fight, flight, freeze, and fawn. Fawn = smiling/laughing, being agreeable, engaging in conversation/people-pleasing behaviors in order to avoid conflict and appease the predator until you can escape. It's a pretty effective way of getting out of a situation alive but it's also kinda fucked because the lack of consequences just reinforces the predator thinking this shit is okay. (This is pretty much exactly how I acted the last time I was harassed by a jeet driver. I felt really guilty about it afterwards but hey at least I didn't get raped lol)
I hate the fact that the stinkiest, rapiest, most depraved people on earth are the exact people who choose to work a job where they're confined in an enclosed, unventilated space with lone & often vulnerable passengers at all hours of the night.
I firmly believe that taxi/uber drivers should be vetted in the same way as hospital workers, childcare workers, teachers, etc. They should be forced to undergo a police criminal record check and vulnerable sector check. Optimistically

I'd also love if they had to submit to a psychological assessment, reference checks, employment history, etc. just like cops. You wanna drive lone, vulnerable, drunk women in the middle of the night? Then PROVE you're not a rapist/sex pest. No proof, no taxi job! No like, too bad, go work at Singh Hortons.
