Some people are going to behave like self centered jerks not matter what their mode of transportation is. I can understand not having the light sensor pick you up and having to skate through a red, some sensors won't even read a motorcycle. As for me, I regularly wait for lights to change. I stay off the sidewalk. I take paralel streets to main roads when I can. I don't know if I help our collective image at all, but I don't get a whole lot of hostile behaviour from motorists when I bike within the law and use some common sense and manners in traffic.
