I'm sure there's an "in Russia, ski lift ......'s you" joke here, but I can't find it.
Scary stuff. I'm guessing transmission failure of some kind, but where are the emergency brakes?

I paused at :12 in full screen and it looks like the brakes are down...but like I see a lot on the slopes, it does little to stop a runaway once it gets some momentum.

are ski brakes not a thing anymore?

I hate fucking Marmots -- they eat battery cables and brake lines (yes, really). They're a plague up at Mt. Rainer if you park your car overnight. You'll see cars covered with blue tarps held down by rocks in the parking lots of the park: those are hikers trying to keep the fuckers from eating anything rubber on the car.

yup, he hit the brakes as soon as he noticed the guy wasn't going to shoulder check... Maybe he could have hit the brakes harder and sooner, but why would you assume the guy wouldn't look? to brake that hard when the other car was still in it's lane would have made no sense and been more dangerous in the conditions.. this guy with the dash cam did nothing wrong.

also in Canada we can have partial fault in accidents too. % of fault allocated and dispersion of insurance follows suit. so on a bicycle, you can be found partially at fault if you got hit, but since there isn't insurance for bicycles, only the driver's insurance would have to dish out.

Except that you CLEARLY see after heavily accelerating to pass 2 cars he hits his brakes and slows down when the other guys blinker goes on.

He accelerated to make the light...that's his mistake.

According to this study, even without antilock brakes and accounting for reaction time, 30m is plenty of distance to stop at that speed. Sorry.

Not 100% of the time. If the light had turned red while the car turning was in the intersection waiting to turn (almost what happened here), then they turned and a car runs the light and hits them, going straight, it's still the second cars fault.
BUT
That argument still ignores reality, which doesn't care who is legally at fault, it's the biker that will pay the price, so logically it's the biker that needs to be more careful. In this instance, he wasn't careful enough...or was, but just barely.

Your video, Pump your brakes kid, has made it into the Top 15 New Videos listing. Congratulations on your achievement. For your contribution you have been awarded 1 Power Point.

But bikes can brake much faster due to being 1/10 the weight. My bicycle has far less contact and stops on a dime.
I'm pretty sure some new bikes have abs too.

Well as for the braking, bikes actually can't break as fast as a car often due to very tiny tire contact patches... breaking hard on a bike can be quite dangerous! My car can stop WAY faster than any motorcycle I've owned because with the car you can just slam on the brake and abs kicks in. and tons of tire contact. Also this is probably a go-pro or similar, so wide lens and everything looks way further than it would have appeared to the rider.

Predicting someone might turn left is impossible?!? Wow. Don't drive anywhere near me, please.
Also, sometimes a bike can brake better than a family car?! Unless you're comparing bikes with broken brakes to cars with high powered aftermarket disk brakes, that should be always.
It sure looks like a blinker at second 4-5, but I could tell he was turning by second 1-2.
Neither of them were blameless, imo.

Rewatch the video, when it starts the light is green.

-The time on the video is 1 second in when the light turns yellow
-His speed at that time is 54km/h, default speed limit in Canada in urban centers is 50km/h but plenty of stretches are 60km/h, decent odds his 5k under versus over.
-The time on the video when his front wheel hits the stop line is 3 seconds.


From that we can say the time from the light turning yellow, to him reaching the point he needed to stop was 2 seconds. At 50km/h, lets work out the distance. 50 km/h works out to 13.9m/s, so the moment the light went yellow he was maybe 28metres from the stop line.

Australian government says that dry road stopping distance for a family car at 50km is 35m. Now, sometimes a bike can perform better braking, sometimes it can perform worse, but it doesn't seem that it's obvious a biker should be able to stop in 28m the instant a light goes yellow, seems that passing through is not only prudent, but quite likely the only option that physics allows.

The MSF courses all tell you that you need to never enter a corner going too fast. You can speed up a bit or maintain, but having to use the brakes in a corner means you're splitting your traction between cornering forces and deceleration. Also, using the front brake makes the bike want to straighten back up from a lean.

This guy dropped his speed by 30mph from when he entered the corner to when he went off the pavement. I don't believe him when he claims that his steering locked up.

Exactly. In a different video he claimed that the steering "locked up"...um yeah, I think it's more likely he was going too fast and braked while trying to turn into the corner and quickly learned what understeer is.

He's not taking it at 40, he's going into it at 70 and braking while in it. No wonder he went over.
