    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...

    2020.40.3 and Regen

    After upgrading to 2020.40.3, I feel a difference in the way regen acts. Is anyone else feeling a difference? I felt that the regen is less than I expect it to be in some situations and sometimes it starts with less regen when I lift off and then increased regen right after. I always have my SOC...
