Sometimes when you are on a bike, cars don’t seem to care about your safety. Well, you could get mad about it or you could throw one of these magnets at the offending vehicle. It lets them know that they’ve acted like a jerk and calls them out on their behavior.
The card is designed by Peter Miller for cyclists. Just hurl it at the offending car and it will stick, without causing an accident. Later, the driver will feel bad. Rightfully so.
