It's not always because us car-drivers are talking on cell phones that we almost hit you motorcyclists.
It's because motorcycles are so damn small, and because people who drive them frequently drive them too fast and change lanes too often - I can check my blind spot to make a turn, and by the time I turn my head forward and do it there can be a motorcycle that has weaved into the blind spot, completely hidden from my mirror views. This has happened to me. I have almost hit motorcyclists several times, and not because of talking on my phone - because they and their bikes are too damn small. They almost always proceed to flick me off as well, as if I should have some sort of 360-degree camera on top of the car watching out at all times for assholes.
Don't take this as an insult to you - if you drive your motorcycle at reasonable speeds without a ton of lane-weaving, anyway. Also, if your motorcycle is quiet and doesn't disrupt everyone's conversation and dinner within a 4-block radius when you unnecessarily rev the engine.
In the same vein, I hate trucks. I can't see a damn thing when they're around me and I'm trying to make a turn, or when they're in front of my shining their lights directly at my eye level. Most of these people don't need to haul anything anyway - and they've got a bald-eagle-and-American-flag stencil on their back window, along with a Calvin-pissing-on-opposing-truck-manufacturer sticker.
