So what do you think has happened in minutes before the video really started? Regardless, what it was, I just don't seem to come up with something which would make me ever to pull over and do as the guys have. I mean even if she has done something very wrong traffic wise who do you think will the cops believe now, looking at the short video clip and a testimony of three people???
Maybe she brake checked with God as here guide; or started slowing even further to impart her safety minded values on the aggressor... but yeah, totally agree, it takes a special kind of special to stop in the fast lane of a 400 series for a driving lesson/cat-call.
