While I think you're right, I do want to correct you on something. Class 8 trucks like the Tesla semi have an 80,000 pound total weight, hence the name 'Class 8'. Typically the truck and trailer weighs 32,000 pounds leaving 48,000 pounds for cargo. Average cargo weights are in the 35,000 pound to 45,000 pound range. If the Tesla semi significantly raises the empty weight of the truck it will limit the amount of cargo that can be carried. A load of toys will be nowhere near the weight limit but a load of milk products will easily exceed it. Some states allow increased Class 8 loads as high as 115,000 pounds, mitigating the weight issue. My guess is that Tesla will try as hard as possible to match the weight of existing trucks. It is interesting that they haven't released weights, perhaps because they don't yet know or because it is bad news. If it was lighter I imagine Elon would have mentioned it multiple times in tweets. https://www.teslarati.com/how-much-tesla-semi-truck-battery-pack-weigh/ https://www.teslarati.com/how-much-tesla-semi-truck-battery-...
