Airbags should deploy as soon as the two vehicles make contact.

Note: The airbags that we often see in movies and cartoons inflate slowly as if someone was inflating a balloon. If that were to actually happen in a real-life collision, the people would be crushed to their deaths long before the bags even begin to inflate. In a real situation, airbags fully inflate in the blink of an eye. It's an actual explosion, and that's what is necessary in order to cushion the occupants while the collision is occurring which may take only a few milliseconds (a few thousandths of a second)!

Note2: If you want to actually see how the airbags perform in slow motion, you must increase the simulation frequency to 1200Hz, then run the scene. You will see the airbags deploy in time to protect the driver!

Note3: Modified timing so that shortly before the crash, the sim frequency automatically switches to 1200Hz so that you can see the crash in slow motion.
