I might as well repeat the overprotective parent perspective. Fatalities are higher if you're in a sedan in an accident with a pickup or semi. There are a lot of trucks on the road as well. Finally, road accidents are the one of the biggest risks young people face.
So ignoring the fact that this makes it into an arms race of weight and size, a parents desire for child safety wins against someone's desire to lower carbon emissions.
