As damaging the road, do they more than 'normal' car because of the weight. BUT this is more relevant in Canada with the freezin / unfreezing of the road, maybe not relevant in the US.
Most people who have a SUV use the 'I need to transport my family safely' argument. First, SUV arent safe do some googling and you will see ( I have no time for this since I am already trying to figure out the size of the internet (see other thread)). A normal car can carry 2 adults and 2-3 kids without any problems. If you need more room, get a mini van! Oh... you dont want a mini van because it doesnt look maleish enought? I think I have touched a point here... People buy SUV because of the look. I have too agree, they look good! Then they try to find justification to buy them... Look at all the ads for SUV, how many people that you know who own an Explorer are going to use it to work in the field or even go out of town with it? Not much... If you want security, you would get a Volvo...
How can it be dubious to understand where your liberty stops? It has to be one of the easiest test of judgement one can make: we teach it to every kid. Dont do to others what you dont want them to do to you... You being a normal balanced person ( I had a neighbourd who thought listening loud music at 2am was ok).
I am loosing myself here... The point is just that SUV are big poluting cars who give a false sense of security. I will shut myself now, it must be unpatriotic to talk like that about SUV, or it will soon be!
