Rodger B I agree with your first post, subdivisions are at 30MPH but the southern streatch the NJ turnpike is at 65MPH, one is too fast the other too slow. But disagree with your second post, if you are on a public roadway with multiple lanes if someone attempts to pass you on the left you should move over and let them by. The reason being is they may very well be an unmarked car etc. In NYC it is not uncommon for police to come up from behind on the left side on boulevards in excess of the 35MPH limit. They don't want to hit the siren because that would tip off the bad people they are trying to sneek up on. They will often radio a marked car to stop the left lane squater down the road and issue a ticket. Mind you the ticket won't stand up because the officer witnessing the offense didn't issue the ticket. But most will just pay it.
