Swedish Police estimate a speed of ~250 KM/h (for the U.S. folks, that’s 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 3m (10 feet) from where the collision took place.
Basically the bike was functioning as a missile.

wow, did the passengers get hurt?
no they where fine…
everyone was killed very terrible
