Two speeding motorcyclists were cut off by the same car and crashed into it, but have no one but themselves to blame. Excessive speed gives motorcyclists less time to react, and is more difficult to predict by other traffic participants. It also looks from the video that the road on which the motorcyclists were speeding was already busy, which alone should have been the reason to keep to the speed limit. By cutting both of them off, the driver probably saved an innocent life.
It doesn’t look like the collision was fatal for either of the motorcyclists, which is a pity cause sheer arrogance motorcyclists demonstrate on the road is a good enough reason to want them all incapacitated. Motorcycles are not as safe as cars, but high incidence of accidents is primarily a result of reckless and inconsiderate riding, not lack of safety features.
