OMG, that's not just lane splitting... that's some batshi*t crazy stupid dangerous disregard of other drivers, traffic laws, and the laws of physics. Hitting twice the speed limit, racing out on blind intersections, traveling on the the wrong side of not only a double yellow line, but one with traffic-blocking bumps down the middle, on blind curves, nonetheless.
If this were a true test ride, I'd never sell a bike to that jerk! Other than that, it was exciting to watch.
Remind me not to ride in Korea.
