It makes sense. Long roads, and there are many in Texas can take far too much time to feel any progress being made when you are stuck at 65 like many states or 55 even. I pity such states as they are usually Democratically controlled.
Notice how the Democrat controlled states just steal your freedoms in any way they can. Its all about the power.
No, it doesn't. This road is in the Hill Country near Austin, not out in west Texas where there's nothing around for miles and miles. This will have major traffic. If it's posted 85, they'll be driving 100 mpg. Just imagine the carnage when there's an accident.
Try crossing Nevada on I-80 sometime. No matter what the speed limit. It was the most horrible, boring trip I have ever made.
