I'm sure I will get flack for this, but I bet most will agree silently in their own heads.
I joke that I feel that whatever speed I happen to be going on the road is the correct speed. Anyone going a few mph faster than me is a crazy idiot and anyone going a few mph slower than me is a moron that needs to get off the road.
I read somewhere that they did a survey and found this to be true of most drivers.
