Oh, usually here in Illinois, you're only supposed to spend just enough time in the passing lane to get around slower moving traffic then get back over in the slow lane, and then you shouldn't even be running any faster than reasonable to pass a slower vehicle. Technically, we shouldn't be speeding or running slow enough to block traffic. I don't see many people get pulled over speeding unless it's in an area that is watched closely and I haven't ever see anybody running below the limit get pulled over for restricting the flow of traffic.
