It's a moment that could have severely injured (or worse, killed) this motorcyclist — a car changing lanes abruptly across two lanes during heavy rain.
For all intents and purposes, the motorcyclist (who barely escaped grievous hurt on the roads) had every right to be enraged over the reckless spot of driving. When Donny eventually caught up to the driver and knocked on her window however, he didn't give her a piece of his mind — he simply laughed it off. What a proper champ.
