If I'm the first one to the light (bike lane or no bike lane) I take the lane, because I like to see how long it takes a car/cars to catch up to me from a dead stop. That's the sprinter in me.

If I'm on a road without a bike lane, I simply take the lane -- all the time at a red light -- in the exact way a car would, i.e. If I'm the 6th person to the light, I take the position of the sixth vehicle.

If I have a bike lane, I stop way back from the light and once it turns green I sprint and find a gap and take the lane thru the intersection, that way I'm in no danger of a Right Hook.

Also it's amazing how long it takes five or more cars to get thru a light that turns green; although, I find this as an extreme form of frustration when I'm in the car driving.

But on a bike, it's just amusing.
