<i>Not everyone in Germany has a 300kph car.</i><p>No, but the German expectation is of a 200kph car. So a 4 fold increase in the power consumption over American cars is quite reasonable. (Americans are just a bit north of 100kph on the highway. 100-120)<p>Higher speed&#x2F;power consumption over shorter distances&#x2F;times is actually bad for EVs, because the time spent waiting for recharge vs. driving is proportionately worse.
