americans and driving

[Wren57]

Surface roads are 40mph around here, and the interstate loop around the city is 55... I normally go with the flow of traffic on the surface roads, which is normally about 45... on the interstate I keep it at about 70 so I don't get passed left and right... I used to drive fast everywhere, but now the only time that I really "speed" is when nobody is around and someone wants to race, and even then I don't race too long because it is dangerous... just race for 15seconds or so for some fun, then shut it down before I get going 100, because that is way too fast on surface streets, even with no traffic
