Anywhere with sensible traffic schools. Accidents are almost always caused by drivers going 10mph faster or slower than the rest of traffic. Being the odd man out in this criteria is dumber than ignoring some numbers on a sign that everyone else is ignoring.
EDIT: Since it's become apparent it needs stated for those of you who missed that week of Driver's Ed, and didn't read the manual; One: I merely quoted the manual; Two: it is INDEED the job of EVERY driver, regardless of their position relative to specific other drivers, to take any actions neccessary to avoid or mitigate an accident in the making. Idiots like you are the reason No Fault states exist.
Anything less than 5mph over the cops consider suspicious where I live. 6.2 mph over is slow-lane, but at least reasonable.
