Best I can find in Canada is in BC. I think you could get longer distances in a few other provinces, but the issue is a lack of roads/destinations in the northern corners, haha.
But that's crossing a country. Texas is a state. Going from San Diego to Portland, Maine is ~46 hours, and that's probably not the longest route. There's also Alaska and Hawaii (no direct roads to the contiguous 48 states), and Florida, that's just a pretty long route off the top of my head.
Your geography lesson for today is to map 2 routes across the EU and compare them to your statement.
Map the longest route across the continental EU.
Connect the farthest points of France by way of Paris and compare it to the distance between Hawaii and New York. (Hint: Start is in South America or the Caribbean and finish is in the Pacific. )
Lol, I always forget how much random stuff France owns across the globe.
But here's an overlay of the EU on the contiguous 48 US states from Reddit (doesn't include Alaska, which is half as big as the whole US). That even gives the EU UK, which is no longer a member state. Alaska is really really big (like more than half the size of the lower 48 states).
