I always thought that using several tons of steel to move a single person from a to b is ridiculous. I can't imagine a bigger waste of resources like gas, ore, end road infrastructure to only have people confined and isolated to their car seats, couches, and office chairs. Millions of people strap themselves to their seats in their cars with belts, voluntarily imprisoning themselves in small coupes.
Don't take me wrong, when I lived in California I absolutely loved my car. I drove a Volkswagen and it was the only thing I shed a tear for when leaving.
In many cities there's nothing to do but eat, mostly sandwiched between a couch and a television, and the car.
In well developed cities you can stroll which is take a walk and look at landmarks and people without having to buy anything while simultaneously exercising.
