@JFC Fuller :
It seems to me like the new Mustang E-Trash (to fast haul family garbage to your closest trash disposal & recycling container) doesn't have any appeal. Ford built the (Mustang) Probe in the late 80's that had the finest Cx in the world for any mass production car until Testla came. They could have done much better with their first proposal to the electrical car community, especially rebranding the Mustang name.
The E-Tron doesn't have any of the performance advantages of what Tesla offers, nor in price or specs.
Focusing on the Tesla design, you have here a unibody design (a monocoque chassis) that is still rare in the pickup truck segment to make it a weird choice for a PR stunt. It's a lot of design work and production tuning to get to there where a simple body on frame would have done it faster and cheaper.
Given also that they test drive the thing with civilian passengers,reaching scarcely seen acceleration value (equal or better than Lambo specs) I very much doubt that they would have taken the risk and the pain to reach that level only for their marketing division.
The lack of wipers and side view mirror might only reflect a search for new technology. This pickup is built to offer damage & degradation tolerance and this might be part of that philosophy.
There is also the fact already mentioned that this is a market already saturated with owners that tend to stick to the same brand/ same model. So the economical risk are higher than their previous endeavor. If they can past the test with a cheaper to build model (tooling with a drastic drop in body panel number), something that seems to be a new focus for Musk, then it will open the door for new opportunities to build cheaper to make models for a
clientele only looking for the specificity unique to Tesla: high power battery, quality built, specs and cost. We might even see a Tesla model competing with entry model (an Austin Mini wedged like?).
