Residential and local downtown I do pretty much the speed limit (25 flat). Downtown they're known for pulling people over doing 27-28 at times, so no messing with that.

Main streets, 0-5 over typically. Highways it's 0-8 over usually, just depends on the situation and how I feel. Lately I've been fine more and more just setting my cruise to 70-72 and letting the passive aggressive fools duke it out in the left lanes.
 
In normal driving conditions, about 6-8 over on the freeway; on surface streets I'm at the limit or less.
