Guess what, I used less gas and not just because of the smaller car. I would have still used less gas and scared fewer people if I was driving the same car as you.
And what did it get you? You got to park about 4 seconds earlier than me. 4 seconds. Was it worth it? Was it worth the stress you caused and felt? Was it worth the extra gas $$? Was it worth nearly killing a person?
I doubt it.
