I'm guessing you either don't remember or didn't see what SUVs and light pickup trucks looked like in the 80's and 90's, but there is absolutely a lower bound on size that is way below where we are today.
This is probably the case. The truck is between the size of a Tacoma and an F150, and the SUV is about the same size as a Tahoe or a Range Rover. Certainly not small, but not strangely large for the US.
Pickup trucks haven't always been bigger than parking places. We should be selling reasonably sized vehicles of all needed configurations, not these monstrosities.
