SUVs have lower cargo capacity than more fuel efficient vans, and often even less than cars like old Foresters. They 100% serve no purpose, but people have been tricked in to believing this lie about cargo capacity.

Even trucks today have lower cargo capacity than vans, while also having worse fuel efficiency.

But lets for s second assume this lie is true. Why not require a commercial license for any vehicle built on a truck frame? Prove you need it and you could get an exception.
