You could wear as well a security vest. I did this for a time after almost being hit by an RV on a small byway. It looks ridiculous but being alive is nice!
I don't miss riding my bike in the states. People are simply not used to seeing and/or looking out for bicyclists. Of course, depends on where you live really. My friend in OR owns a house and three cars but he prefers to take the bike to school every day. People stop and ask him if he needs a ride or help because they think 1) his car broke down, or 2) he is poor and needs a hand. At least Americans are nice! These Germans are quite another story. I will stop ranting now.
