The little truck isn't legal to build and sell in the US. Truck sizes have exploded since 2012 because that's when the CAFE standards changed to be based on vehicle footprint instead of vehicle classification.

Suddenly small trucks were required to have the same fuel economy as a hybrid sedan. So small trucks are out and instead of making them more fuel efficient they just make them bigger every refresh to keep up with increasing fuel economy standards.

That's also why think the Dakota, Ranger, and S10 all suddenly disappeared at that time. The Ranger came back, but it's larger than the F150 used to be.

It's also why small cargo vans just stopped being a thing. Ib the last 3 years the Transit Connect, ProMaster City, and NV200 were all discontinued because they couldn't keep that size and meet CAFE standards.

Of course, none of this applies to the Cybertruck. Fuck that thing.
