Fatal Car Accident in NJ

What would the average passer by be able to do for this person, or, what was a person?? They hit the concrete barrier at about 60mph and the car burst into flames. Unless you have a Delorean that can time travel, your not going to be able to help them. Plus, there was a police officer in a Charger that arrived about 6 seconds after the point of impact. I also heard that the driver had a history of seizures.
