I saw the dispatch go out for that. A similar thing happened to me while getting off 202N at 401. The car came up past us while we were getting off the off-ramp. I flashed him, then called 9-1-1. Didn't see any dispatches for accidents over the next hour or so. Figuring he realized his mistake and turned around.
