Are you going 10 mph??? How the hell are you getting that?
The fastest speed limit that I've dealt with so far is 55mph, so the fastest I've gone is about 65. No WOT runs yet, but plenty of jack rabbit starts around town. I even commented to my friend that I might be in the market for tires pretty soon.
I almost shit a brick when I clicked onto the trip meter to see what my average was and it was over 16.
