Is it socially acceptable to speed?

I speed, a lot. On highways, backcountry two lane roads and such.
I don't drive like a dumbass, I am aware of my surroundings. Probably much more than the idiots tooling along at or under the speed limit.
In town, or near houses I obey the speed laws unless it is the middle of the night when I am obviously the only one on the road.
I don't race anyone on the street any more, or even play with them. If boy racer wants to shoot ahead in his shitbox car I let him.
