Ok as a mechanic a few million questions:
* What happens when a wheel seal goes? Do I have to remove all that ridiculous plastic on #2,3 axels??
* What happens when a tire blows? Is it going to destroy all that plastic and take out a few more tires in the process?
* Why all the glass? I've spend entire days replacing windshields for a 12 or so truck shop which generally come in two (drivers and passengers), the Tesla semi would require a crane and expensive replacements.
* Why is there no bumper or frame attachment points? Bumpers save the truck from damage, no one wants to buy $xxxxx front end, lights, etc when a deer in the bushes jumps into the middle of the road.
Honestly from my point of view it seems Tesla tried to apply personal EV to a semi. Did they do any research from tractor shops or mechanics? There is a HUGE reason tractor/trailers are easy to service.
