Ahh, i would off course expect an American to tell the unadulterated truth and NEVER exagerate on any topic...
So wow, 300k, unbelievable, plus,they have Looong highways and in majority of states its a 50mph limit....
Majority speed is 70mph on all express ways/interstate Some are 80mph and some are 90mph (texas) and some there is no speed limit
