I've been riding motorcycles for the last 8 years and when driving a car I show any fellow motorcyclist the same road manners as I would expect when riding myself. As Souk said, don't tale gate, keep a watchful eye out, and we are not all hooligans
Too bad lane splitting is illegal in MD/VA or I'd be riding to work more often. If you try lane splitting on the beltway during rush hour, you'll most likely be the lucky recipient of a front fender sandwich from some a-hole who doesn't want you to make faster progress. Folks are ruthless out here. The motorcycles have been left for weekend fun, unfortunately. BTW: for the brave soul who does try his hand at lane splitting, I try to make room and pray
