It's usually the exact opposite way round – distances between things in the US are usually larger, not smaller, than in other countries. You only need to look at a world atlas to see that's the case, with a few obvious exceptions. What in Europe would be seen as an extreme road trip across a whole country (because it would take a whole day) would seem quaintly short by US standards (because it could be done in just one day). Hearing it said the other way round sounds very odd to me (and I'm not from the States, as my user name suggests).
You are right, my mind was set for coastline which is very populated. This is not the case when getting more into the middle. But main concern was on charger locations. I don’t know what is their status in inland.
