I know I'm asking a lot of q's here, but I'm anxious to do all this right. Is driving from mailbox to mailbox for like an hour or two a day really bad for you car? I'm a really great driver, but know next to nothing about auto mechanics. I have a nice car and don't want to mess it up stopping too much. Of course I don't put it in park, but, it's still slow moving and a lot on the breaks isn't it? Yet it's much faster than walking to each box, especially when the insert boxes are space 2-3 houses apart; cause not everyone has a newspaper or flyer box.
