Get yourself a cheap action camera

I got an action camera from Temu for under $20 and mounted it on my bike facing backwards. Drivers have been SOOOOO much more careful around me, it's insane. Some people won't even pass in the lane next to the bike lane, they'll switch to the lane further over then pass. I highly recommend! Honestly it probably doesn't even have to be real since they just see the camera, think they're being recorded, and give the bike lane appropriate room when passing me.

Only thing is that it probably doesn't work for nighttime driving unless you put some reflective tape on the action cam case.
