It depends what the speed limit is. I'd say slam on the brakes if you're going 30 but accelerate through if you're going 40. But of course it all depends on how close the other driver is and how fast he's traveling, how much warning you have...
My point was that there are going to be times where speeding up will work better. Saying "100.00% compliance with the speed limit" is never going to cover all cases.
Or how about if you're already going the speed limit on a four-lane road in the second-left lane, a guy is coming up on your left, and some bozo starts wandering into your lane from the right. There is also someone right behind you. (This actually happened to me.) Your only options are to violate the speed limit, or let the guy hit you. Me, I tried to split the difference between the two cars and ended up hitting the guy on my left instead.
