Good points A bit more detail on what I've read, the banking was designed for 130 mph to be used by high-speed convoy troop transports. I'd expect your usage description to be the norm, but to fight an on-continent war, I'd expect that they'd close the roads, and send through the convoys, and since 2899mi / 24h is 120.8 mph, it'd be doable. The Cannonball Run is indeed approaching 24h seems to have just gotten to 25:39[1]! Of course, they have to deal with normal traffic out of NYC and into LA, and avoid cops the whole time. With the the cops clearing the roads and any street-legal car allowed, I'd bet under 17h would be the norm [1] https://en.wikipedia.org/wiki/Cannonball_Run_challenge https://en.wikipedia.org/wiki/Cannonball_Run_challenge
