I would suggest that non resident aliens visiting the US do not attempt to create their own autobahn. Over 90 mph you can face charges of not just speeding but also reckless endangerment, reckless driving, arrest, excessive bail or no bail because as a foreigner you could be judged as a flight risk, and suffer confiscation of cash, credit cards, cell phones for investigation, etc..that will leave you broke and stranded.

All traffic court judges are locally elected or appointed and usually eager to convict. However if you are stopped you are under no duty to admit to any lawbreaking, but over 100 what ever cop is chasing your will be thinking is that the vehicle is stolen and or driven by drunk or a meth head. few states let police estimate speed by visual observation but so many state police agencies use a myriad of unmarked cars, lidar, aircraft,  now that unless you get really lucky it would be extremely risky to drive at over 100 for more than a few moments unless you are so far out in the sticks that the only officer covering that area is drinking coffee miles away. But so many drivers and truckers will snitch you out so dont  think that passing at hi speed won't get you noticed. Merry Xmas.
