From one of our regular correspondents, at Drive and Stay Alive, Inc., we received the following photographs and brief report:


The white bit, at the right-hand side of the hole in the side of the car, is the clue.  


The graphic display (below) was placed at the Stockholm Motorcycle Fair by the Swedish Police and Road Safety Department. The sign above the display noted that the rider had only recently obtained his license.

The Honda rider was traveling 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 side of the slow moving car at an intersection. At that speed, they predicted that the rider's reaction time (once the Volkswagen came into view) wasn't sufficient enough for him to even apply the brakes. 


The car had two occupants and the bike rider was found INSIDE the car with them, along with the motorcycle itself.

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 the car, plus the rider) were killed instantly. 


At 250 KM (155 mph) the operator is traveling at 227 feet per second. With normal reaction time to SEE-DECIDE-REACT of 1.6 seconds the above operator would have traveled over 363 feet while making a decision on what actions to take. In this incident the Swedish police indicate that no [such] actions were taken.
