I’ve done sustained 140 MPH on German Autobahns in a Mercedes and was nervous as hell. This is TWICE that fast!
I once drove about 15 miles at 140 between Crestview, Florida and Pensacola. I was doing around 75 on I-10 when a Porsche passed me.
I decided that this was my chance to drive fast so I hung around a quarter mile behind the Porsche for a few miles at maybe 85. I guess he got tired of my following him and sped up to what I later determined was 140.
I floored the old F-250 with a 460. I had done several things to improve it’s performance but it was still not a dragster. On the other hand, flat out running at 6000rpm seem to be it’s forte.
I stayed with the Porsche for maybe 15 miles then decided to slow down. About the same time, I noticed the temp gauge was all the way over to hot. Good thing I slowed down when I did although the old pickup was actually running smooth as silk.
When I was young and stupid I did 120 in a Ford Escort.
It pegged at 80, but the car running next to me went up to 140 on the gauge, plus I knew just based on the time to clear the distance it had to be close to that.
