Oh man, the main reason I took the LAB course was that I was having confrontations with drivers almost every day, and said so when I introduced myself to the class.

Sure enough, on the road ride, I got honked and yelled at twice. In both cases, they singled ME out from the 4-5 riders in the line. Got great laughs from the group. (One was a "get in the bike lane" as we were making a left hand turn).
