This is a clear cut case of wrong place, wrong time. A motorcyclist was riding along the docks of a harbor wave in Portosole, Sanremo, Italy. A security camera on a yacht happened to catch this intense moment. A rogue wave came over the wall and was so strong it took out not only the motorcyclist, but also the cars that were parked near there.
They have a nice video of freaque wave occurrence, go take a look of it!
