Cool! I never knew his name, but in my pre-heated gear days, I used to compare myself to him with all the layers I wore commuting.Bibendum the Michelin Man
My first time of having my airbag vest deploy wasn't any kind of spectacular tale. But it taught me a valuable lesson. I was heading to the prison and evening rush hour was in full swing. I came to a busy intersection, stopped and saw the traffic starting to move in the lanes ahead of me going right to left. It was a huge intersection, so I knew there was a few moments if I turned now, that I could get out in front of the traffic to my left. I let the clutch out and looked forward...to see a teenager carrying a skateboard crossing in the crosswalk. He wasn't doing anything wrong, BTW. I hadn't begun moving more than maybe a half mile an hour???...but my right foot wasn't on the footpeg yet. My only choice was to grab the front brake hard and keep from hitting the kid.
The next moment, I was looking up at the sky and lying against the curb. Huh?? What happened? Oh...the airbag vest went off. I can see the bike sleeping on its side a few feet away. I do a quick check and everything seems to be fine for the body and it dawns on me that this should hurt. Hurt bad. My back is laying against the hard edge of the curb and I hit hard. But no broken ribs. Why? The airbag did its job.
I rode away with a badly bruised ego and a dirty jacket and airbag vest that used to look so pristine. I bought a new CO2 cartridge for about $22 and washed the vest.
If my understanding is correct, an airbag with sensors wouldn't have deployed. That would be a stop and drop. But I'm sure I would've had some broken ribs from that encounter with the curb. The tethered system had the airbag vest deployed before I hit the ground. It also had my airbag vest deployed when I hit the ground in 1/30th of a second. It works. All the other arguments for a sensor activated airbag are IMO simply marketing arguments to convince you to buy that instead of a simpler system.
As @dduelin said, I've tried to walk away from my bike a few times and always been brought up short. The analogy of wearing a seat belt is good. I think I'm smarter than the seat belt, and decades ago I learned how to unbuckle it before getting out of the car. I learned the same thing with my tethered airbag vest.
