While they most likely do not "really need " a range rover for that, it is a choice that they have made. I don't see how some of you guys can preach about "being part of the problem" here. While you may not have a large SUV (as it would seem in your view to be part of the problem), some of the SUV owners do not not have three, four or what ever the number of power consuming systems sitting in a home that could easly service 3~5 more residents. Or maybe they wonder why does one person live in a 3 bedroom home, or need more than one car ect.
I am not saying that either way is right or wrong, just that we all have a view on what is or is not "part of the problem". That being said we are all at the mercy of that black gold. Don't like it, I feel your pain. But the fact is for the next 20 years or more it's a part of our lives. We are just now tasting what Europe has digested for more than 50 years.
