It is a testament to Elon Musk's vast skills at producing obfuscating noise that nearly all of the discussion of electric semi trucks here has been about the Tesla Semi, and not about trucks made by the many manufacturers who will actually sell you an electric semi truck.
In a way it's a testament to the lack of marketing skills of the truck companies that are selling these vehicles. Perhaps they don't feel the need market their capabilities to people who don't actually buy trucks, but there are some benefits to that kind of above-the-line advertising. As Musk has demonstrated.
