Valid points! We thought about these things, but we had limited time and we couldn't get to them. As for the route suggestion - this isn't up to us. It depends on our data source and what results it returns.
Thanks @GrumpyNI, I'm currently in Amsterdam, you guys sure as hell have a lot of Teslas :) Happy we've hit the mark, although our calculations are based on estimations, we've done our best to keep it as relevant as possible.
