This happened just outside my home this evening. Was walking down the street heading home this evening, as I arrived at my block there were blue lights flashing all over the place; Police cars, Ambulances and Fire trucks. There was this accident and the Fire crew dismantled the car to pull out the, apparently, injured driver.
By standers who saw the accident claim that soon after the accident the driver was walking around talking to the other driver that hit him. After he took his details he got back in to his care and called an ambulance. While one might conclude it was an insurance claim stunt, it’s common for pain to be delayed. He may well have had internal bleeding that only hit him later.
Anyhow here’s a video of how the crew dismantle a fairly new car and extract the driver.
