Food industry try to make people eat more, way more they need, to get higher profits selling food or industrial food, despite healths risks as obesity, diabetes etc...
Vehicles industry try to make people use more cars, have more cars, or just bigger cars (more expensive to manufacture) to get higher profit, despite polution, climates problems etc... Bigger cars it's the new fashion, and some people have a bit selfish feeling about it, since a bigger car will destry more the other cars (if smaller) and suffer less damage or have a bit less danger to driver. So people try to get a bigger car destroy the other, maybe in a freudian point of view.
Where it will end?? In cars like this?
This
"Titanic Automotive Complex"...
The need to feel huge like if that could gave a sense of importance.
