I know I've said this before
This is Texas. The left lane is the fast lane.
The speed limit on the interstate is 70MPH (not KPH-like your home counrty) . In Texas the speed limit is looked at as a suggestion (well, so are red lights). 65MPH is SLOWER than 70MPH. It's slower than 75 and 80 MPH which everyone would be going if you'd F*CKING move over.
