Is it so hard for the cars behind to slow also? Saves gas and brakes to slow well in advance rather than hauling ass up to the light and braking. I happen to know pretty well how long the lights around here work. I play it accordingly. If you see me rolling along toward a green at about 30 you can go ahead and pass me. I'll bet I pass you before you can get through the intersection. Assuming to don't pull back into the lane I'm in and make me slow even more. Also in the summer it is really nice to keep the breeze coming. Plus your shoes/boots get hot after several stops at lights do I'd prefer not to put them down any more than necessary.
Gernerally I would agree with you. But around here that just seems to invite somebody stopped further back in the next lane over to jump in front of the slow-stopper at the last second, causing them to jam on the brakes. It's much safer to let them over during acceleration, if they actually have a reason to get over. That is, if bikers had the courtesy to let anyone over ever...
