I've had drivers rage at me for just make the signal for "put your phone down". Oh! I once had a woman swerve her car at me as rode by and I asked why and she said it was because I gave her a dirty look. (I gave her a confused look when she went straight with her signal on).
Gravel InfluencerA really fun calculation you get to make as a cyclist or pedestrian is, "Will this driver attempt to kill me if I flip them off for nearly hitting me?"
