Which Wheel Do You Put The Metal Core On Vehicle Airbags?

Vehicle airbags? - which wheel do you put the metal core on

My friend has an accident, such as V-Day, when the airbag is used. That's what his father wants to do:

1. Cut the glass and put a metal plate on the bike, then the hole tape.

2. Pop a hole in the airbag and put on the tape and the hole.

How do you convince him not secure and do illegal? Everything that I said what he said was a pitcher of garbage and refuse to hear.
