The Honda rider was travelling at such a "very high speed", his reaction time was not sufficient enough to avoid this accident. Swedish Police estimate a speed of ~250 KM/h (155mph) 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 enough for him to even apply the brakes. The car had 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.
All three involved (two in car and rider) were killed instantly. This graphic demonstration was placed at the Stockholm Motorcycle Fair by the Swedish Police and Road Safety Department. The sign above the display also noted that the rider had only recently obtained his license.
