You don't always get a pass up to 80MPH in Texas. I've got written proof

Seriously, it depends greatly upon the location. Out in west Texas 80MPH or more is tolerated, except in certain areas that are known as speed traps. Big Spring - a small city that is several hundred miles from the nearest population center - is a good example. I've seen troopers there pull someone over and issue a ticket for ~3MPH over the limit (70MPH) on Christmas day. I kid you not. It definately ain't about traffic safety at that point.
