Also caught the lack of helmet and then everybody backing away. My experience with accidents and heart attacks is that people first rush in to see and then freeze or back away.
Presuming the fat guy in the suit owned the Beemer, his total response was not to help, no curiousity about the kid under his car, not even joining the crowd to lift. His response was to pull out his cell phone and cross his arms. Incredible!
The police response could have been better too. The first officer pitched in to lift the car somewhat. But after the kid was out, he's wandering and talking on his radio, not even seeing if the kid needs basic aid. Most officers see a lot of car fires and so should know that the fire was far enough away. There were also two officers, so could have split their efforts. Maybe it was just human to focus on the bigger attention getter.
When the second cop finally gives attention to the kid, after knocking down the fire, why in the world were they trying to pick him up and move him? The fire was no longer a threat, the kid was presumably breathing (chest moved a couple of times) and not bleeding out. Basic response training is that major trauma should assume to have back or other internal injuries and to limit movement. With two cops and an instant crowd, this probably was an area with ready EMS, so the response should have been to simply keep him stable for the ambulance. Fortunately there was somebody who recognized this, coached the officers, and they listened.
In the end, I have a kid that age, so get well young Mr. Wright.
