Dual Sport Rider rear ended on Bishop near Hespeler Rd MacDonalds today seemed unhurt

I heard a loud crumple like a lot of water bottles were being driven over... and looked in the lane beside me to see a Dual Sport bike under the front bumper of a small car!!
The rider was already being attended to by car in front ,,, and he seemed fine.,, the OLD OLD guy who rear ended him was still trying to focus on what had happened..

hope he gets on ok!
