I bet Tesla sells a few of these. $300k for the long-range model. If a standard semi costs $200k.
Fuel cost per mile with the Tesla would be around 23 cents/mile compared to 58 cents/mile. At 100k miles/year, that's a $35k/year savings. I would assume maintenance would also be a lot cheaper.
With the lack of megachargers, I assume these will not be used for long haul. My dad went from driving OTR to short haul, where he would return to the terminal every night. I think these make up almost 1/2 of the trucks on the road.
