What is going on ?

One pitch black night I was standing near a very busy life- risking road and some people sped round the corner like wild animals out of control. Their car went into a skid and rolled completely over it was a black, sleek hatch back Bmw , but in seconds it was a reck. I thought to myself is that person hurt or not? the person was hurt the car was upside down windows were smashed into tiny little pieces I couldnt help from calling the police and ambulance if I didnt they would have been badly hurt they got straight to the hospital they got treated
