Most people don't need an F-150 with a combustion engine, but that doesn't stop them from getting it. In much the same way that they won't need a 3 ton electric truck, it won't stop them from getting it.
If the production incentives were different, there’s no reason we can’t imagine they’d have tried to code rugged manliness as a rugged 4x4 like was popular in the 90s or an absurd muscle car like was popular in the 70s instead.
Which is worse?
If you are discussing trucks and want to talk about gross vehicle weight you should probably clarify that is what you are referring to.
The F-150 Lightning weighs just over 4 tons.
Also, you got it wrong. F-150 is a half ton, correct. The F-250 (and 2500 from RAM/GM) are 3/4 ton. While the F-350 (and 3500) are 1 ton trucks.
