The Honda CRX was famously cited by auto journalist David E. Davis as a minimal car he'd be willing to drive on the Autobahn with. That only had just a bit over 100 hp and could just barely make it past 100mph. My point isn't that German cars are overpowered. My point is that they aren't really, but they're still expected to be able to hang with it on their highway system. If an EV is going to have a sharply reduced uninterrupted highway driving time, then the unavoidable minimum charging stop time of 30 minutes is going to have a proportionately larger impact on travel times there.
