I think he was talking mostly about good motorcycle airbag vests like the Helite Turtle and e-Turtle. "Good" is an important qualifier word though, the worst airbags offer little protection and don't limit head movement.

This is a great video about the Helite Turtle (it came out before the electronic e-Turtle) and motorcycle airbags in general.

I'll definitively grab a Helite e-Turtle when I start riding next year.
