that has happened to us on a ride one day, 100 kmh zone, I was the 4th bike back so did not realise what has just gone on until we pulled over, a Late model camira decided to pass another car and was on our side of the road, the lead rider was quick enough to signal to the driver to pull off the road and we basically rode through the middle of 2 cars doing 100 kmh while we were probably a little faster than that , at the time I was thinking why was this guy driving so fast off the side of the road but on the wrong side
