You are correct re the Powerwall and Powerpack confusion. I had gotten the information off of the Wikipedia article and accidentally combined information from the two tables.
That definitely changes the cost/weight/power equations.

Now throw in the autonomous factor. Subtract driver labor costs and throw in near 24/7 operation (vs. human drivers which are required to stop for rest breaks).
Semi doesn't have be electric to be autonomous, Frieghtliner is already showing diesel autonomous prototypes.

True, and to those add the cost of externalities like mining on natural ecosystems and pollution on climate warming and our health.
Are recharge breaks less time than human breaks?

I suspect battery swaps are on the agenda.
Musk wants $100/kwh cost from the Gigafactory, but market is currently above $300.
Semi tractors only weigh 15-20k lbs your talking a battery that weighs as much as the tractor. 300 gallons of diesel is 2000 lbs and the engine and transmission is about 3000 lbs. it would be at least 10k heavier which reduce carrying capacity since gross is capped at 88,000 lbs total not to mention space.
