Texas FM roads are excellent and usually in West Texas dont have much traffic. I well remember driving back from Lubbock one night in 57 after a Texas Tech game going toward Midland. The speed limit was 60.I was doing about 70 in my 54 Chevie. Alone on the road almost;; very straight road. Then in my rear-view mirror I see headlights far in the distance. I look again in a minute and see them much closer. Soon a car passes me as if I were standing still.Much have been going at least 120. Not too long before before the tail rights were so far away they seemed to merge. Moonless night so I never saw what kind of car it was.
That was the fastest I’ve ever seen a car go on the highway, by far. I was near 80, and I think he was twice my speed. I’d been on the Autobahn and Autostrada in the early 90s, but the areas I was driving, they were about as congested as some American highways. There wasn’t room to go that fast.
