You can get by with significantly less than 1/N I think. The goal doesn't need to be infinite travel distances, just enough to get to the next destination. Personally, I'm unlikely to drive more than 1000km in a day. Any more than that, and I need to rest for longer than it takes a car to charge. If electric rails are placed in the road frequently enough to extend the range of an electric car from 400km to 1000km, they've suddenly made electric more practical than gasoline for long distance travel.
