Men of reddit, has there ever been a situation where you were alone with a woman and felt physically unsafe?

I ask because I had that happen to me one time. I was young and idealistic, and I saw a woman begging for a ride on the side of the road. As soon as I picked her up, I started to feel something was off. She kept trying to get me to drop her off at this location I knew was deserted at that time and out of the way. She made jokes like, “Don’t worry. I’m not a crazy killer.” I “accidentally” drove past it and dropped her off at a very public gas station, but to this day, I’m pretty sure she had someone waiting to mug me at the very least. That’s the last time I picked up a hitchhiker, no matter how sympathetic they looked.
