80 is my 55. Sometimes 90. 80 is a pretty regular speed, but 90 really pushes it here.
100 really isn't that hard, you just don't get to do it for very long (at least I don't). I'll typically hit and break 100 if it's like >11pm and there's nobody on the road anyway. I'll book it til I meet up with traffic again. I might be a jerk, but I'm not a moron.
