I think one of the only reasons that GA is targeted like this is because we're such a small demographic. Now you can do a lot more damage to a structure with a Ryder truck or a minivan, but if metropolitan areas began to restrict having minivans near high density areas, people would lose their minds.
For a while, they restricted large vehicles from certain areas of terminal parking in PHX and you should have heard the people screaming 'foul!'
Not that I'm endorsing restricting moving trucks and minivans from certain areas, but the entire assault on GA is largely ludicrous.
