What they were saying is that that's a barrier to making their fleet electric. "Available EVs don't have the clearance to do the job we need for our fleet." whether it's true or not. I agree with you, and my model y is lifted.So you're saying that the NPS does not permit EVs to drive on sand? To me a vehicle having "clearance" is a mechanical elevation problem, not a rules problem
What they seem to be doing when they talk about EVs is going on tangents which may or may not be barriers, rather than focusing on what can be done and moving forward.
