What do you guys think about bumper stickers?
On one hand, I think it's good that people want to share their ideas with others.
On the other hand, I think it may do more harm than good by distracting drivers. The fact that you are diverting some one's attention from driving to reading something is bad enough. But if you're message is something controversial, it can also have the added effect of offending some one, and consequently making them agitated-not something you want to do to some one driving a 3000 lb vehicle at high speeds.
