When I was a teenager, I was riding in the back of my friend's car one day. I was wanting to be less uptight about shit and had delayed putting my seatbelt on. When I did go to put it on, I realized it was caught in the door. So with the intent of not being as uptight and asking my friend to stop for a second so I could open the door and free the seatbelt, I decided to just open it while we were going, pull the belt out, and close it again.

Right as I was reaching for the door handle, friend takes a hard left turn, pushing me hard against the door I was just about to open.

I took a moment to appreciate how close that had gotten to going really bad and that one needs better situational awareness to do something like I had planned before opening the door to get the seatbelt out when I was sure he was just going straight.

Though it would have been kinda funny (albeit in a horrifying kinda way) from their perspective to suddenly have a passenger fall out of the car while it was going.
