Actually, Tesla is taking orders for their new electric Semi.
It has a range of 500 miles on a single charge, many companies are buying fleets. They cost about $180,000 each, which is not too bad by Semi standards. A brand new Peterbilt truck costs between $160k to $330k and prices go higher for custom designs
It was supposed to be in production by 2019, but got delayed. The cool stuff is always delayed.
If you want to order one, you have to plunk down $5k, and then pay another $15K within 10 days.
