> You wouldn’t generally exceed 15mph street skating.

I don't have a dog in this fight, but I wonder what the velocity of one's head hitting the pavement is if you just stand still and fall over.

That's 0MPH, but it still seems like it'd be enough to do damage.

I watched an old guy die in a parking lot because of this. His hat blew off, he bent over to pick it up, and then fell forward onto his head. He died soon after. Now, he could have had some kind of other issues leading to this (he was elderly and had mobility issues). My wife parked while I ran over to render assistance, I called 911 while a military medic tried to revive him but it was too late.

So yeah, that can be enough (might have been a heart attack as a result of the shock, I am NOT a doctor, but he was gone by the time the ambulance arrived).

Also, one of the reasons street fighting is so dangerous has nothing to do with MMA dudes, it's when someone falls down and hits their head. This happens all the time. They sometimes die from the fall.

> You wouldn’t generally exceed 15mph street skating. Competent downhill skaters can reach 50mph+, with world record speeds exceeding 80mph.

it's all context, no?

You wouldn't try to trick over a 17ft drop on a longboard, either. [0]

Sheckler has done bigger and many kids do more than 17ft drops for fun. When it comes to falling in street skating there is a certain pattern to falling and knowing how to “fall correctly” almost like stuntman do without helmets in movies all the time. Stuntman do sometimes wear padding, but not always.

Bombing a hill is very different from skating a stair set. The speed at which you do tricks is manageable to be able to tumble your body correctly if you fall (and you’re ready for that fall usually) but bombing a hill is an enormous amount of speed and you can’t prepare yourself for an unknown rock that throws you off.

That’s another somewhat important difference too with street skating, for big tricks you triple check the area and often sweep it because of those tiny rocks.

So context does matter. I’m not advocating against helmets but these are incredibly different things.

Edit: and fwiw I’ve hurt myself far more bombing hills than I have skating something like the big four in ATL. Notice how they fall: https://youtu.be/Ban0D24Aip4

(And the reason they aren’t making this trick is ironically they are not going quite fast enough)

Edit 2: and because I’m reminiscing a bit, the big four is hard because the run up is pretty short. You need good bearings and small wheels to gather the speed required. The only time I’ve ever seriously hurt myself in 15+ years of skating was doing a dumb trick in a standing position. Helmets are important for things like vert for sure where it’s lots of speed and lots of height, and if my kids and I go out and skate we wear helmets (they’re small and I want to set a good example). But most of street skating can be treated as though you’re a trained stuntman (because you basically are)

That’s the way it is! If you’re going to do stuff like that, learning how to crash gracefully is something you should learn up front. Tuck and roll!

Agreed. For what it’s worth, I think street skaters should wear helmets most of the time.

The 17ft drop is equivalent to the 80mph example in my post, and should definitely involve a helmet, gloves and impact padding (which can be worn under clothes).
