I think it's wild that people spend their own money to surveil themselves every second they're near their car. Maybe I've seen too much lawyering on TV and in movies, but if I'm in a collision with you, I'm definitely asking the cops to pull the SD card from your dashcam.
Whenever I point out I think this self-surveillance is crazy, the response ends up sounding something like "oh, no big, if I think I did something wrong I'll just hide the evidence and lie to the police and say it doesn't work", which sure doesn't sit right with me.
