European here. Maybe I'm not typical, but I know that the contiguous US is about as large as the EU (around 4000 km from one side to the other). And if you need 24h to get to the other side if a state, you're either on dirt tracks in Alaska, or got stuck somewhere in the worst traffic jam ever. Texas is about 1000km wide, just like the larger european countries, that's a 10 to 12 hour drive.
