In over 50 years of riding and have had a lot of mates who been involved in serous bike accidents, most have had broken/injured legs, arms, feet and hands and no marks on the body wearing leather/bike jackets, my best mate killed wearing a full face helmet where the chin guard hit his chest and snapped his neck and not a mark on his body, my point is would an inflatable safety jacket stop you getting injuries where most bikers suffer most injuries.
I been down the road a few times in my 50+ years, first time hit from behind stopped giving way to on coming traffic waiting to turn in to my mate place and the car went over the top of me, left knee injury at 17 years old, then a few years later a car stopped in front of me without brake lights and clipped his rear bumper, same knee again when it got hooked on the handle bars, and last injury 8 years ago when my Norton decide to throw me over the handle bars at a slow speed emergency stop, fractured left arm and broken left thumb, no injuries to the body in all them accidents, I have also been down a few time on cranking the Norton over and pushing it to its limits in tight twisties to find gravel all over the corner from cars leaving blind driveways.
My point is always wear a good leather jacket or bike safety jacket, a good helmet and boots, I don't wear gloves and I still have all my fingers and open face helmet that fits right and I still have my good looks.
If you do come off in a slide, never tense up, roll with it but it's easy to say that but go limp and you will come out with less injuries and you might walk away from it, all depends on the seriousness of the accident.
Some accident we have no control of the outcome, but that's the risk we take every day in our lives.
Fear and worrying about what might happen can be more dangerous when riding, I never think about it, I just enjoy my time on the bikes.
