None of them. The floating platform causes a resistance in swings which start slowing them all down. Those that are off rhythm the most get more resistance. Eventually, like an asymptote curve on a graph, they all begin to converge on each other.

Also like a asymptote curve they may never actually achieve a %100 sync because as a metronome begins to match its sync more, the more the resistance against it lessens, but as the resistance lessens the amount of force to correct it is less.

My grandma had it and a few of my friends. They all had different signs of it at the start. Some trembled very soon, some had symptoms like a completely other disease and some didnt show much of it until it massively broke out all at once.
All I learned from that is that you cant say if people have Parkinsons or not over the Internet, unless its very obvious. It can start slow, just like most other diseases, and can have symptoms that arent that obviously linked to it. It actually took a year or so until the doctors of my Grandma identified it as Parkinsons and she didnt have trembles until much much later (about 5 or 6 years).

meh. As a sexual artistic video, I think all aspects of it fell a little short. The music was fairly uninspiring, it was almost elevator music level. The choreography starts slow but interesting and then never went anywhere, choosing instead for set pieces where the girls just goofed off.

As far as the costume went, I liked most of it, it clearly was ment to objectify the women as horses, although I think the mouth brace could have been done away with. It makes the outfit look less cosplay and more S&M attire.

It doesn't take much variance in speed to cause annoyance in other drivers, if this device tells you to slow down even 5km/h (sorry I don't do miles), you're going to be breaking the flow of traffic and people *will* overtake you.

People drive up to and often slightly over the speed limit, you can say whatever you want about what people *should* be doing but it's not reality, so it's moot.

If this doesn't take other drivers in to consideration, the entire thing is pointless other than the light countdown timer, which is handy but could also cause irresponsible driving ("If I speed up now, I'm gonna make it, this thing is switching in 5 seconds!").

What else is it telling you? Start slowing down now but oh wait, 5 cars just took position in front of you...guess the distance I calculated to the traffic light just then is no longer useful, you better slow down another 10km/h, oh hell just look in front of you and slow down to meet traffic conditions.

Ok thanks computer!

There is also an expectation that technology works and it is entirely valid, yes people should use common sense but this doesn't excuse your product for not working, this is silly. The purpose of technology is to work so transparently, you are doing less thinking so you can focus on more important things, like sudden high impact situations that require heroic reaction times.

Anyway, I don't think this is bad tech, I think it is not particularly useful in today's environment and is just an odd stepping stone to proper smart cars. I think the gradual progression to smart cars is the fault of an uneducated public who have unfounded hate in the concept of letting go of driving to a computer.

I just want smart cars every where for everyone, so we can have safe and effective roads.

I disagree. It SHOULD be a PSA for defensive driving, but instead it's a scare tactic to try and convince people that driving 7km/h over the speed limit is killing the children of hard working folks.

This PSA puts the emphasis on the speeding as though it's the problem. The real defensive driving lessons people need to prevent such an accident have nothing to do with speed. Obviously the guy driving out in front of the oncoming car should never do that, and that's not a small mistake, that's a kill myself and everyone in the car with me mistake. Lastly, the more important point that lots of drivers could stand to learn is regardless of if you are speeding or not, watch the road ahead for cars that might cut you off, and if it looks like they are start slowing down. If I spot a guy coming in too fast on a stop sign ahead, or rolling up to it, I slow down even though I have right of way, just in case. 9 times out of 10, it turns out it didn't matter, but it has spared me an accident on more than 1 occasion where even a little below the speed limit, there was just no way I was gonna slow down.

And the 7km over IS a ridiculous line for the PSA to draw. Just compare the difference that extra speed makes to your stopping distance and time to the difference in judgment required of the guy pulling out. The guy pulling out is gonna misjudge the oncoming traffic arrival time and distance by more than a second or meter or two.

*promote this *commercial, it starts slow and then transforms to awesome. Also the *money scene is doubly awesome.

Starts slow but gets awesome at the "How to piss of a girl" part!

This reminds me of a fun story my dad would tell from his naval days.

There was a bunch of guys getting flow out to some base in BFE. Long, boring flight, nothing to do but...well I guess messing with the flight crew sounds like fun! So, all of them start slowing creeping to the back of the plane. Planes have this thing called trim which you adjust to level out the ride so you don't always have to give input into the controls. So after about 15 mins of them slowing moving to the back of the plane, the trim is set at a pretty aggressive downward inclination...then everyone dashes forward at once.

This sends the plane into a nose dive. The flight crew realize what is going on quickly and recovers the craft...but then he gets a little fun on the controls and starts bouncing them off the floor and ceiling for a bit. Good ol navy fun apparently. I would of been cowering in the back.

was hoping for someone to start slow-clapping towards the end, 80's style!

That is a very nice building, it would be beyond my pleasure to be able to walk through it slowly--at my pace. As well as watching the cars being built themselves, it would be great. It's really a place were you might play a nice score on your iPod while sipping champagne--if they would let you...

Talking to the individual people sound as though it would bring the whole experience together, but none of us are so lucky as this interviewer, so I guess we get to take his tour as our only ever example. I wonder who gets to wander through those halls though...? Besides the obvious choices of course...

BTW, if anybody reads this before watching do yourself a favor and bump this up to 720p and throw it on your HDTV and watch it there, as it is the length of a documentary anyway--watch it in relaxation.

It was a more entertaining piece than I thought it would have been as it started slow, but the visuals kept you engaged.

//Which is a good thing to do for a great many videos here on the Sift BTW; just stick them in a playlist or find one of the many playlists that already keep track of them...

as maestro has astutely pointed out, you've errantly assumed this truck can full stop in zero time. Hurp de durp de durpidy pthhhhhhhhhhh

Seems likely to me that he'd be able to brake faster than the truck could break, and if the truck started pulling too far away leaving him exposed, he could coast on the shoulder till he can safely stop.
I'm not saying I would do this, but it doesn't seem all that dangerous. I guess the one thing to worry about would be road debris, since he can't see it coming.

I dont think its about who can stop the fastest, its about how fast you can start stopping.
He's about half a metre away from the back of that truck. He's doing 90kph. Human reaction time is about .2 of a second. Lets do the maths.
90,000m/3600s = 25m/s
25m/s 0.2s = 5m
He's going to travel 5 metres before he even starts slowing down. If that truck has to brake hard he will go into the back of it. Granted, his speed relative to the truck won't be very high but it would prolly be enough to send him arse over tit. at close to 90kph. and he aint exactly in leathers.
I'm not even sure he could stop faster than the truck. Sure, the truck is heavier, but it has 4 wheels, big thick tyres and a lower centre of gravity. Lets do the maths.
The coefficient of friction between road bike tyres and average russian tarmac is...no I kid.


No I didn't? I just assumed the truck would slow enough that he could go into the back of it. So ok, the truck travels 4.8ms, the bike travels 5m. He's now 30cms from the back of the truck, and only now is he gonna start braking. Assuming they decelerate about the same, and I'm not even sure you can stop faster than a truck on a bike, there is still a 3m/s difference in speed with 30cms of room between them. Like I said before, he won't be going very vast relative to the truck when he collides, but his wheels are still going to be spinning prty quickly and I'd guess that would be enough to put him on the pavement...or you know, the risk is large enough that I wouldn't want to try it.


And this is ignoring all the myriad other risks from travelling at 90kph blind. Maybe his attention is on somebody in a car with a video camera in the lane next to him, and suddenly his reaction to the truck braking is delayed...maybe a pothole appears under the truck. Or a puddle. I'd rather base jump than do that.

I will downvote this.
Not because of the event but for the way that it is edited. The beginning is cut off and all that remains is the violent act itself.

There are better, more conclusive versions of this video that are better and explain context for what is happening. Yes, it's akin to a mugging. It is a racial attack buy a group of teens mobbing a white male. It starts slow and then escalates from there.

This video sensationalizes the end result and focuses only on part of it. Therefore the video holds no water. I suggest finding a version that is complete, or better yet has some news commentary with it.
