The proposal would allow the Texas Department of Transportation to
establish a speed limit not to exceed 85 miles per hour on a part of a state
highway system, as long as engineering and safety studies determine the higher
speed limit is appropriate.

Eighty-five miles per hour would be the highest posted speed limit in the United
States and the second-highest posted speed limit in the world, according to the
European auto rental firm Rhino Car Hire. A speed of 140 kilometers per hour, or
about 86 mph, is posted on some motorways in Poland.

It's always tough to keep up with the hang glider pilots flying
for World records out of Zapata.
