Cars are cool because they revolutionized the way we travel and live our lives. We are now more capable of working, traveling, or attending college out of state. (And more things I can't even mention in one post) However people buying expensive cars, or more cars then people in there house are not cooler for it. It does not lower the coolness of that person either it has little to no effect on the coolness spectrum (a scientific term I think).
Cars that use gasoline to power them are bad for the environment. They release pollutants like carbon into the air. Carbon kills us all, leading to fear. Fear leads to anger. Anger leads to hate. Hate leads to suffering. If we continue to use cars with gasoline, then will will all join the dark side of the force.
