Ask me anything on the injuries/mechanisms or whatever else could be related to car/bike crashes and you might want to know.

Have you ever thought that Darwin was right and to hell with it all?

Mostly with bikers, but I uphold the Hippocratic oath.
Besides there chances are bad anyway.

Older cars/cars with less safeties than modern cars.
For the risk, is the potential injuries worth it?

Fiat 500; how fucked is some girl going to be if she gets a collision with this blob of a car.

Should I get the glass in my car replaced with some form of shatter resistant plastic or does it not make much difference in a crash?

Depends on brand and models, old Volvo's are usually still pretty decent because the interior compartiment doesn't crush easily which keeps the steering wheel away from you.

If you hit the steering wheel that's usually game over: your large vessels can rupture, your lungs can bruise beyond repair, you can get a severe hematothorax, your can have a myocardial contusion, etc...

New 500? If she hits an object herself: pretty good (depending on speed), they are though little cars with a strong shell, the short deceleration can rupture stuff and her seatbelt will give rise to abdominal injuries but better then being crushed.

If she hits a large SUV then her chances are worse. Mass is a killer.

Keep the glass, plastic can buckle and invade the interior.

Helmet without HANS on track days, yes or no? I have a padded rollcage and I'm wondering if the added safety for my head is worth the additional load on my neck.

Fuck Darwin and braaaap

HANS > no Hans, a head is top heavy already without a helmet and in a crash will fling about crazily, easily injuring the cervical spine which can easily lead to paralysis or worse a dislocation of the vertebra with spinal cord transection which results in death.

HANS keeps your cervical spine from excessive and violent motions.

Your padded roll cage will not stop your cervical spine from flexing.

What would you do scenario

>victim comes in with RT Talus fracture (it's in half)
>RT ankle swollen ~4x normal signs, tests show early signs of compartment syndrome
Go
