Factual error: The paramedics apply the neck collar to Kick Ass after he was hit by the car. The problem is he is already on the spinal board when it is applied. Neck collars are always applied before putting the patient on the spinal board, especially when head or neck injuries are suspected as would be the case in being struck by a car. Even if there were no witnesses to him being hit, paramedics would assume a neck/head injury if no one saw the incident. Also, the paramedic doesn't immobilize his head before applying the collar, and is far too rough in putting it on.
