T I watched Engineering Explained videos when they first came out last year, not to mention watching the Tesla Semi live on it's drive to San Diego in December of 2022. (I've watched his videos since inception on YouTube for years...) A meaningless statement, since EV trucks are useless if they aren't towing anything significant That's a ridiculous statement. They can easily take 80% of the load of a class 8 truck. Then there is the cost for energy to go down the road. BEV wins every time vs diesel costs. Then there is maintenance costs. My Model S beats any ICE on energy costs per mile down the road. Even a dinky 200 lb. motorcycle! So just scale that up to a semi. The ratios don't change. Of course aerodynamic drag will be higher but electrons still win. Eric

This guy does a heck of a job explaining the problems with the Tesla Semi: That guy doesn't address some other important factors that are relevant in over the road rigs. 1) Drivers are limited by federal law as to how many hours per day and per week they're allowed to drive, and time spent fueling up counts. The old days of popping white cross dexies to stay awake to drive long hours are long gone. 2) Most over the road (OTR) company drivers are paid by the mile, not on the clock, so down time for frequent battery recharging will substantially restrict the miles they can legally drive, and subsequently lower their paychecks. Delivery costs go way up. Or drivers just quit. 3) Owner operators are paid by the load and weight limits and multiple hours spent recharging EV batteries every few hundred miles can make for money losing (and fewer) trips. 4) Refrigerated (reefer) trailers require a separate power source (diesel) to keep their motors running, even when the truck is parked. OTR sleeper cabs require a power source for heat and AC for when the driver is off duty and catching some shut eye. 5) Weather is another important variable in battery range. EVs, whether car or truck, do not like very hot or very cold temperatures. Substantial cuts in range under either condition. These points are just a few off the top of my head. Electric truck mandates by some arbitrary xx date are totally impractical and unworkable. As I said before, OK for some local delivery trucks and vans, but for OTR big rigs, no way, in spite of professor Eric's delusional fantasies..
