Re:Insurance costs could fix this (Score 1)

Of course, that would further hinder the poor - who almost always own older cars/trucks, which are in general heavier and more likely to cause mass injuries in an accident. This is particularly an issue in the US; many poor families own an old pickup truck, which is also used as a work truck.

As a general aside, SUVs and trucks have full length rails in order to support a more capable payload and suspension capability. Without the full length rail, the capacity would be limited. Cars used to have this as well, except that it became too expensive...
