Fore sure, the commercial protections pads are a minimum that don't guarantee you to survive any crash. Remember: At more than 27 km/h on a frontal crash, the brain crushes itselfs... so what's the point of preserving bones with jelly into the skull?
Personnally, as a previous customs motorcycle officer, I managed a study on safety devices for motorcyclists.
A this time, there was no crash pads at all: cotton vests & trousers, or leather for winter, or simple cotton shirt in summer.
For the same price than the pair of cavalry shiny rigid boots we had, we could have a full gear equipment with goretex inserts, back, elbow, shoulders and knee impacts pads, real motorcycle shoes allowing to move our feet...
But no way. Tradition...
Then I saw two colleagues crash, with nothing than cotton jacket on them.
One was following me, very quick (170km/h). A car suddenly stopped with no brake lights in the middle of the road. I passed at ist right but my colleague did not see the car before I ducked, blocked the front wheel, fell on the road and smashed the back of the car at aprox. 100 km/h. Just him, its bike crashed another car in the left lane.
I was sure he died instantly. I met him moaning about its brand new shirt he ruined. Not any broken bone. The car was salvaged, the rear wheel was just behind the driver's seat.
The other ran after a car going wrong side on an highway junction to prevent a crash. An oncoming car smashed him at aprox. 50km/h (it was a very steep corner). He walked away with just a broken wrist. And died 2 hours later of an exploded spleen.
Then I quit.
I heard that another colleague had a crashed after he received real motorcycle boots, and they were really efficient! His feet had not a single bruise, because they stayed in the boots and the rest of the body flew pretty far. What's the point of wearing good boots when a drunken driver shoots you with its car? It's paltry.
I still wear a protective jacket, all the time. Not trousers, except if I know that I'll ride all the day and do nothing else.
The best protection is useless if it remains on the shelf because it's too loud, to hot, to ugly...
The best protection stills to need no protection.
