    Tesla Semi Round Trip Efficiency is 95% on Mountain Passes (Napkin Physics)

    Here is more, and this is so insane that I am still looking for the flaw :-) https://kilowatt.page/tesla-semi-regen-roundtrip-efficiency-is-95-percent/ Based on the 500 mile energy graph, the Semi regen efficiency is insane. Roundtrip efficiency is ~95%, and one way is ~97%. Battery size is...

I am interested in getting an idea of the recovery rate in say the following scenario: You are driving up a 1 mile long hill...
