I'm not going to get in this quagmire of an argument about oil waste, pollution, et al. I just think that SUVs are dangerous because they:

• handle very poorly as compared to the cars that people are ``trained'' to drive
• the physics (mostly center of gravity and momentum related issues) involved in accidents means that in an accident, injuries are likely to be more common and more severe for all parties in said accident
• the fact that bumpers on SUVs are closer to being at car-seated head level than at car bumper level means that the severity of injuries for those in the car in a car v. SUV accident are likely to be greater, and
• their physical size means that they obscure traffic to those behind them, making it nearly impossible to predict shifts in traffic flow
