The mailbox is for efficiency purposes. Does the garbage man come up to your can if you forget to put it at the end of your driveway?
Mail carriers do not usually live where they deliver. Just because your neighborhood was fine doesnt mean the carrier could get out of his or hers. Wonder how much money it cost to tow out all those vehicles at least once ... I also wouldn't expect someone to risk his or her life just so i could get my mail
