Wrong.1. They should not, this would be wrong, this is when the flames/smoke/smell is over and CO is produced. You should be in the car/room/tent at this point.
2. To catch or reflect the downward heat in case you were planning on putting the hot bucket on a flammable surface. Some bricks do the same thing.
The reason for waiting about 20 minutes after putting the hot charcoal into the car is to allow the CO levels to build before getting in so that you pass out right away.
The charcoal will continue to slowly burn and produce CO for many hours after you dump it into the bucket and put it in the car.
