I think there should be a separate license to drive SUVs and Trucks over a certain size. And that maintaining that license should be a bit of a hassle - like a required in-person written and practical test every 2 years. If people want that commanding view of the road and "safe" feeling that comes from endangering everyone else on the road, then they should have to put in some extra effort - not enough extra effort that it's unattainable for those who actually have a need for a vehicle of that size, but enough effort that it would discourage the widespread use we have currently.
