Tesla already said that megacharging (supercharing for trucks) will be 7 cents per kWh in all states, so that truck drivers have predictable costs (unlink Diesel, which can vary greatly).
You might not be American. I had the same confusion when I called 911 to report an accident driving across the US and they asked me if the truck was a "semi".
I’ve been trying to work out the relevance of you driving a Porsche and the weird phasing (you called your car?).
Ironic confusion given the discussion on regional lanagaue variations.
2 kWhr per mile means the 300 mile is a 600 kWhr battery and the 500 mile is 1000 kWhr.
400 kWhr's for $30k means they are expecting $75 per kWhr battery costs. Last year they said it was under $190 per kWhr.
I am very skeptical they can meet that target, $75 would be pretty revolutionary in such a short time.
