A picture is worth a thousand words.

See The Motorcycle?

The Honda rider was traveling at such a 'very high speed', his reaction time was not sufficient to avoid this accident. Swedish Police estimate a speed of ~250 KM/H (155 mph) before the bike hit the slow moving car side-on at an intersection. At that speed, they predicted that the rider's reaction time (once the vehicle came into view) wasn't sufficient for him to even apply the brakes. The car had the two passengers and the bike rider was found INSIDE the car with them. The Volkswagen actually flipped over from the force of impact and landed 10 feet from where the collision took place.
