I get "squeezed" quite often when approaching stop signs. I'm always in the middle of the lane but that doesn't seem to help. The driver will attempt to pass and realize they won't make it around me but they either move over anyway or just stop in the oncoming traffic lane. In the latter case, they'll pull away quickly, moving back into the right lane. I just stop and wait for them to go. I've tried directing traffic with hand signals in these cases but it hasn't seemed to help. Just this morning I had my hand out as a guy pulled around me approaching a stop sign. Apparently he didn't see the car coming in the opposite direction which had to stop (in addition to me having to slow way down) to allow the passing driver to get back into the right lane in front of me. I will never understand this.
