Not sure it should be mandatory but the racing community needs to see if there was anything we can learn from his crash. I have no idea what kind of shape the car was in after the crash but I have seen some pictures of BC in the car with questionable headroom... as I have seen with many other sprint and midget drivers. In my opinion the Tall Cage cars should be the standard height... As a driver myself I would never strap into a car if I had questionable headroom.
