Right, goofed. Saw my error and corrected it on my second post, but it was too late to edit the first. Thanks.Minor clarifications
Model 3 curb weight is 1850 kg, call it 2000 kg with passengers. So 0.77 MJ or 214 Wh net energy to accelerate.
Power goes up as the cube, energy per mile goes up as the square.
Weird about the weight: Had the lbs weight, probably multiplied by 2.2 instead of dividing, so I'm off by a factor of 2.2^2. Correct. Need a lot more stoplights .
