It is however much more spread out. Driving from the northernmost to southern most town of New Mexico is ~700 km. Driving from the southern most to northern most town of Norway is over 2300 km, or about the same has from the southernmost town of New Mexico to the Canadian border.
It's not about the max travelable distance in the country but the max distance actually traveled for most trips. The higher density (and population concentration in the south) reduces the latter and makes maintaining a charging network much more practical (their high adoption rate also help a lot with that.)
Edit: The reason why this is the important measure is because what people care about is how often their trips require N charging stops not the maximum number of charging stops they might have to make.
But what about those living in the north, in the Fjell, and those working in remote spots such as forests? Are those really served well by EVs, and is it really all that sustainable to subsidy EV?
