I hate sounding like a broken record but my belief is that car makers are more excited about XXXXL cars in American than car buyers are. The media is consistently complicit in covering this up, sounding like the brainwashed soldiers in The Manchurian Candidate

It's not to say that we don't like big cars because we do, but walk into a car dealership looking for a small car and they will tell you they are out of stock of new ones of the model you want because the factory washed out in a flood but then they have 100 SUVs in a row unsold that nobody wants to buy made in the same factory. Your only choice is a used return that somebody sold back to them yesterday afternoon.

Go into a dealership looking for an S car and they will try to sell you an L, go in looking for an M and get an XL and so forth. If you drive out with a $25,000 car when you could could of driven out with a $50,000 car they perceive it as a $25,000 loss! No wonder mainstream car brands can't sell electrics.
