Many (most?) F-150 buyers do not tow anything. This is a distraction. It would obviously be possible to make something electric that's better than a bottom of the line F-150, that's what Tesla should have done.
The Cybertruck was a bold vision of the future. Like Daft Punk.
F-150 buyers are not bold visionaries, and that's ok. They are more Kelly Clarkson.
The Ford customers Tesla could have targeted are the ones who never tow anything, want to know they could put a 4x8 sheet of plywood in it (but never do), and who want lane following, good cupholders and seat heaters. That was probably 5% of the F-150 market, which is such an enormous market that even a 5% slice would have been bigger than what the Cybertruck market turned out to be.
