Yes, I know this. But being underway and having to plan my long trip in such a way, that I have to reach a Supercharger every some hours would be a little bit too much hassle for the average German cardriver. Therefore I stated, that every 50 miles on a highway would be ok, as this is something, that would work for long trips within Germany.
