It's not as gay as they say it is.
Also, when there's a stop light, this means that anything that has less than 4 wheels must goto some kind of street pole position at or as close to the front as you possibly can, using any means. This includes lane splitting, riding on the other side of the road, and even the sidewalk. (The sidewalk move was awesome).
And if you want to get a feel of what a Moto GP start is like, just wait at any Paris intersection. The 2 stroke scooters (modified and / or loud) sounds like a 125 start. Every time.
