Don't be so quick to reject. They do take far longer than explosive car airbags to inflate - closer to 500 milliseconds. A car bag must inflate quickly to save the little old lady driving with her face 3 inches from the steering wheel. On my bike, I'm more worried about hitting the ground - which is much farther away. If you look at my previous thread, you will see a YouTube video of a guy jumping off his sport bike as the jacket inflates. It gives an idea of the time involved.
