Actually the problem is not
Actually the problem is not mass production with the semi. The problem is they have not developed a model with more than a few hours of battery power. The sheer weight of the batteries is the major issue as the Tesla models have outweighed your average conventional model by 10,000 pounds. They aren't efficient, weigh so much they basically can't haul any tonnage @ legal weight limits noteworthy of an average truck load. Also and you tech geeks can't absorb this, transportation companies can't afford a 50 percent increase in equipment cost with zero charging infrastructure in place. Side note, to convert every truck stop and rest area in America to electric charging and changing all power grids would cost an estimated 700trillion dollars and counting. Note, are very few grids that can handle the power load of charging 500 trucks a day/night. Imagine plugging 9.4 million nationwide a night? People need to think, this is a 25 year plan not a 2 year plan. Something else to think about, your electric bill just went from 150 a month to 1,000+ a month. Wait for it.....
