I was in Germany in 2012. I drove 120 and over on the Autobahn. It was rather boring after a few minutes and I was getting passed regularly.
There are a few roads in America (I think in Montana) where there are no speed limits. But the cops can give you a ticket if they think you are going at an unsafe speed. So do like we used to do when I was younger. Find a nice long stretch of road. Drive it to ensure there are no surprises, then run it to redline. Much more fun.
“There are a few roads in America (I think in Montana) where there are no speed limits.”
A couple of times in the past but not any more. Reasonable and Prudent speed law was thrown out after it was deemed to be too vague. A clown from back east (who claimed to have been a NASCAR driver) got busted for driving stupid and blew it for everyone.
