Efficiency was brought up to explain the real problem, range. I didn't fill up between Reno and SF in my F350 towing a massive trailer and still had plenty of fuel to spare. A cybertruck would've barely made it past Sacramento with a much lighter load and would've taken much longer to fill up.
Actually from Tahoe to Sac is probably one of the better stretches to pull that off, it’s all downhill.
That doesn’t change the gist of your comment however - which is correct. (I’m a happy Bay Area Rivian owner who’s made that trip often)
Tahoe to Sac for sure isn't bad. The uphill section before that adds 2-3 gallons by itself when I'm towing though (compared to a flat route the same distance and speeds). IIRC net fuel economy winds up being similar to a flat stretch (even the downhill stretch burns a lot of energy in your brakes and has enough flat and uphill segments -- slightly ameliorated with regenerative braking, but I don't think it moves the needle enough).
How is your Rivian by the way? Is it in any way comparable to a cybertruck or is it just far and away better?
