I'm wondering if a bike advocacy group such as LAB has thought about producing public service commercials. Motorists should be educated on simple concepts:
Cyclists have a right to be on the roads.
Adults cyclists do not belong on sidewalks.
Bikes are vehicles and follow the same traffic rules as cars.
Bikes are extremely vulnerable to aggresive driving.
I have seen very effective PSA's on the subject of drunken driving, so why not cycling?
