Even while still at 10,000 feet and on approach to the airport, one can see that SUVs make up a significant percentage of personal vehicles; something near 30% I'd bet. This goes right to the heart of national security. SUV owners who don't really need such a large vehicle should all be ashamed of themselves for being so selfish and self-indulgent. And I get tired of having my life put at greater risk due to the unfair match between my energy freindly vehicles, and all of the monster SUVs on the road. This is simply unacceptable. Something must be done.
