I must watch Elevenses more often! Is the presenter any good?

Airbag publicity has blown up recently, but I’m not holding my breath for more independent research. There’s a longstanding lack of it

In MotoGP, collarbone injuries have declined since airbags arrived. But the IoM races must be a more relevant test bed for road riding — albeit, IoM speeds may be too high for regular road crash relevancy.

Regarding regular riders, not all airbags are created equal. Some systems provide relatively comprehensive coverage (e.g. Helite, Astars Tech-Air Race and Street). Others only protect the chest.

Protection varies, too. How many systems achieve CE Airbag Level 2? Unusually for Dainese, I think it might be the only manufacturer with Level 2 airbags (e.g. the Racing 3 D-Air jacket).

Could do with a haircut

Riders have also learned to tuck arms in and roll, about 80 years behind paratroops

But if there's a bit of the body to protect - after the head - it's the legs... study after study shows the frequency of lower limb injuries... lower petrol tanks that don't break the pelvis and handlebars that collapse rather than shatter the femur would be a better investment.

I heard years ago that BMW designed the inside panels of fairings to direct the rider 'up' as they went forwards.

Of course, the option open to everyone is to stand up. Only takes a moment.

At least one of the BMWs was also designed with a weak point in the bars to let them bend. But in theory it's even easier to hit the brakes and stop but as we both know, studies show that many collisions that happen could have been avoided had the rider actually not frozen in an emergency.

A mate (now, sadly, RIP) once said "the Highway Code is wrong. It's not 'thinking distance' and 'braking distance', there's one before that: the 'Oh shit!' distance, where you continue on, at the same speed, without doing anything useful."

It's what I've called 'recognition distance' for donkey's years...

It can be up to THREE seconds before we start to react to an emergency, which is why so many riders fail to pull up or swerve round an obstacle when they had time. It's analogous to Keith Code's Survival Reactions, where we react inappropriate - or freeze and don't react - to a threat.

And the trigger for this delay is SURPRISE!, pure and simple. If we're confronted by a situation we're unfamiliar with, it takes time to recognise what's happening and come up with a get-out-of-trouble strategy.

And that's why sports psychology and tricks like visualisation and pre-performance preparation are so useful - we can prepare in our heads for emergencies that it's almost impossible to prepare for in real life.

And that's why I'm running a live webcast on this very topic online on Wed 11 January!

Surprise, then 'startle'

Although this suggests that:
Even though startle and surprise often occur together, the startle reflex can be triggered without the notion of surprise.

Inflatable cycle helmet already exists, a jacket could incorporate an element of this.

Wouldn't need the full MX helmet coverage, instead a 'sausage' from the nape up over the crown.

They exist no longer https://road.cc/content/news/airbag-cyc ... tcy-305809

And the jeans do nothing for the 'open book' hip fracture typically suffered by riders sliding forward into the petrol tank.

Stand up, or jump. Cheaper and effective.

Interesting in the vid he demonstrates how the shoulder sections restrict head movement, but nothing about front/rear (hyperextension & hyperflexion).
