See Cop... grab brake... crash hard.

What's the worst thing you can do when cornering hard on a motorcycle? Grab a handful of front brake, that's what. This unfortunate motorcyclist is playing in the Mulholland canyons, spots a cop lurking on a corner and makes the rookie mistake of using the front brake really hard which causes the front-end to wash out and the bike to slide away. Not a bad crash, but completely humiliating. Plus, he probably got a ticket too, adding to the value of the lesson.

Would have been safer for everyone if the cop parked further back in the first place. That had to be shocking to see a trooper staring at you on a blind curve out of nowhere speeding or no.

Neighbourhood watch. Some old biddy probably complained for 4 months to get cops on that corner...


Could be a cop too. Using laser speed detection.

I did something similar in motorcycle school. Wasn't going nearly as fast or cornering nearly as hard, and I thought I'd just give it a little squeeze, then BAM I was tobogganing on the asphalt all by myself for 10 feet. Apparently my (helmeted) head hit the pavement -- I didn't feel it -- I'd only had time to think "oh" as things went slanty and then I was down. Bike did pin my right foot against the tarmac for an instant as it hit and bounced, and I was limping for a few weeks.

Good object lesson though. No front brake while in a banking curve. (Some rear brake should be OK. Otherwise you gotsta stop the bank, straighten up, grab the front one before you exit your lane.)

I love the way the cop drives the 5 metres with his lights on. Lazy bastard.


oh, why did he have to crash all the way over there.... grrr. now i have to change from park to neutral to drive.. and then get out...

I think he moved up to protect the motorcycle and rider: shielding them with the car, lights on so that other traffic would see there'd been a crash.

A tire on the road is always static friction, unless you are out of control, like on ice or oil. If it was sliding friction he wouldn't have be able to turn in the first place.

Suddenly applying too much brake in a tight turn doesn't break static friction?

Just to clarify.

In normal operation a tire rolls without slipping, so the friction between the tire and the road is considered static friction. When the motorcyclist hit the breaks, it most likely locked up a wheel or two which made the tire(s) slip. At that point, the friction between the tire and the road is considered sliding friction, which is smaller than static friction. Thus the bike slides out from under the guy.

Good call, clear!

Fucking pigs. They make the world less safe.


So...did you go to school to become that hateful, or is it just natural talent?

I'd have thought you were a supporter (in name, at least) of personal responsibility. Wasn't the cop that didn't know how to ride.
