[the "you" is generic, not YOU specifically]
Actually, you don't need to use a car to do everything. You can't open a can of catfood with a car (well, maybe you COULD slam it in a door a few times, but that seems a somewhat messy solution). On the other hand, you do need your car to drive the five miles to the shop. And because your kitty is fussy, you'll need your car to drive the few hundred metres to the next shop, which will no doubt involve fencing and awkward junctions and weird routing systems turning a two minute *WALK* into ten minutes by car. And don't forget, it's the oil lobby at work here - so there is a REASON why you spend forever at red lights. It isn't your safety in mind, it's to get you to use your fuel doing nothing at all. And since you're in town, you might as well stop at a burger joint for a refill of your own, it isn't as if three hundred and eighty stone is overweight or anything. This is why you drive a Chrysler. One of those trashy cheap European jokes would crumple in the middle if you tried to get into one. This is, of course, assuming you can find one big enough. What's with that "Smart" car? Not so Smart is it, your kid plays with one that's bigger...
For the tl:dr crowd: This eccentric post can be summed up as "American mindset" == "cars" != "doing something without the four-wheeled buddy".
