Not everyone in Germany has a 300kph car. Be that as it may, self-driving capability and V2V should do away with speed limits as well as traffic lights. And, as in high-speed rail, I expect crashworthiness to give way to crash-avoidance. So cars will be lighter and sleeker than they are now.

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)

Higher speed/power consumption over shorter distances/times is actually bad for EVs, because the time spent waiting for recharge vs. driving is proportionately worse.

I would say that about up to 250 km/h car seems to be an expectation based on the manufacturer listed electronically limited maximum speeds for normal German family cars. 2 liter turbo diesel BMW goes up to 240 km/h without any problem, but that is not a common German highway speed, I would put it (based on my limited experience) to around 160, up to 180 km/h.

If you use 170/110 as a ratio, then you still end up with just over a doubling of current battery capacity as a "crossover" estimate point.
