Oh there are definitely good reasons for having a truck, SUV, etc. And I'm sure that eventually you're going to see electric versions of those types of vehicles. Maybe even from Telsa, who knows.
I've certainly thought about getting something like that in the past and there have definitely been times when I regretted not having a bigger car. But I got around the cargo hauling aspect of the problem by having a trailer hitch installed on my little Honda. Unfortunately that doesn't solve the problem for people with families or people who need a vehicle for transporting things on a regular basis.
Although the more I see people on the road driving these behemoths, the more I wonder how much is actual need and how much is vanity.
The only point I was making is that there aren't a lot of electric SUV's, trucks, etc out there right now and although I don't know this for a fact, my guess is that the ones that ARE available or soon will be aren't going to be cheap.
Of course existing models of that type aren't really what you want to call "cheap" either. I just looked up the base price for a Ford F150 - $29k. And that's stripped.
People are going to reprioritize though once gas goes back to 3 or 4 bucks a gallon. And that's going to happen sooner than I think most people expect.
