How to Brake

SwimWithSharks says...

I am surprised he just went right back up to high speed, many years ago while on a motorcycle on a freeway a car in front of me didn't respect the lane being closed and went through a bunch of cones which scattered all throughout the lane: this was basically a couple of seconds in front so nothing I could do but hope that 1) I would hit no cones and 2) that if I did I wouldn't fall down and be run over by the rest of the traffic. Luckily I missed all the cones but I had to stop in the emergency lane afterwards to calm down from the adrenaline...

Why Planes Don't Fly Faster

scheherazade says...

Most airliners have wings designed to be used in low transsonic. They can't effectively go faster. They would literally lose lift if they went faster. Their wing shape is made to only delay the onset of shockwaves on top of the wing (flat-ish top), allowing it to safely creep closer to mach1 than otherwise, but not to operate within/past mach1.

Fan/propeller blades themselves are also mach limited.
(They can be designed to be supersonic, but then you end up with something like this... which in hindsight nobody wants : https://en.wikipedia.org/wiki/Republic_XF-84H)
A subsonic airfoil in a fan/propeller, operating near/at supersonic speed, loses the ability to move/redirect air, due to shockwave disruption of the airflow.

Fans/propellers with subsonic blades that spin at subsonic speeds are effectively speed limited. They lose efficiency above ~500 mph, where they begin to stop generating thrust as they travel faster. Their pitch has to increase higher and higher, until they are no longer much of an airscrew and more of a 'feathered' configuration.

Supersonic jet engines use intake devices (such as shock cones) to decelerate incoming air to subsonic speeds, so the compressor (itself a fan, i.e. a highly multi bladed propeller) can operate on that air to compress it and feed the engine combustion chambers.
Airliners have no intake devices to decelerate incoming air, and they would lose engine compression when entering near mach1 speeds.

Furthermore, their bypass fans (which are glorified propellers) would stop providing thrust.

You would need to design different planes (like the concorde). You can't just throttle up a modern airliner and go faster [than X limit] - like you can in a modern car.

What a stupid video. That is like saying why cars don't drive faster than 30 years ago.

Of course cars ARE faster now, but that doesn't matter when speed limits haven't really changed.

Planes don't fly faster because it is not worth it. Pretty simple.

The Little-Known Patterns on British Streets

Payback says...

Actually, on a snow covered road like that, I would expect people to be going somewhat under the speed limit, in an obvious family neighborhood, over a blind hill. The people also don't know how to drive and/or have improper tires.

Also someone said to move the cones himself, which is against the law.

The smart play would have a "men at work" sign at least at the crest of the hill, but if that's not in the regulations, that's not the unpleasant Comcast guy's responsibility.

You say that as if it weren't foreseeable that some would be driving too fast to stop in the space between where they can see the truck and the truck itself....the accident before they got there proves it's a dangerous road, requiring MORE care if you're going to block the road, not less because it's already proven to be dangerous.
That's a bit like saying 'people get stuck and trampled at fire doors, so we locked them...it's not our fault your wife burned to death, fire doors are a dangerous place, and you just see money to sue at.
Nothing there gave them a reason to ignore safety laws, so Comcast is going to pay for every car damaged. Had they put out the legally required signage, they might be in the clear legally, but they didn't, so they aren't.
Nothing excuses the lack of respect or empathy by the workers either.

Regardless if the comcast guys think they have enough cones out, they can SEE drivers are driving too fast for conditions. And when the slide, they are going to slide right into the boom truck they are working from. Only an idiot would not want to slow those drivers down 1000ft up the road so they don't hit the truck while somebody is up in the boom.

The guy with the videocamera is dumb for not just taking the cones and moving them himself though. Instead of 15 feet apart, make them 50ft apart maybe?

It's true, those repairdudes are shitty, uncaring people and they could've at least improved their safety measures after the first accident. They probably didn't do it right in the first place.
But...
those people crashing, they're shitty drivers. That's a 40 miles per hour speed limit on the road, right? That's 64 kilometers per hour. Look where people slide off the road. Look how far away they are from that truck. That's at least 50 meters. It's enough space to reduce your car's speed on a slippery road to make it safe to break for a full stop. But these people are slipping off the road before they're even close enough throw one of those plastic cones at the Comcast douchebags if they had one.
Again, the repairdudes are assholes but they're not causing the accidents, it's shitty driving. The drivers are breaking too hard and too soon on a slippery road to avoid a truck that's too far away to crash into.
Just take your foot of the gas, use your breaks just to reduce speed. If you're not driving an automatic, shift down a gear to further reduce speed when you're slowed down a bit. Once you're slow enough, like maybe 30 kmph or less, you start breaking for a full stop.
Don't stomp on your break 100 meters away from the obstacle. If you start sliding, release the break to regain control of the car, to get out of the slide.
Also, why isn't the actual scene of the accident secured? Why doesn't the guy who slipped off the road secure his own damn car? I don't know about the US but over here I'm required by law to have a warning sign in my car that I have to place 100 m down the road. That would probably placed before the hilltop, where people are unable to see the repairtruck. They would be warned that something's wrong down the road.
The idiot filming puts out more cones (or whatever those things are supposed to be) but her places them by the truck instead of securing his own crashsite. Instead of warning people coming up the hill, he berates the repair-assholes and shoots video of more shitty drivers crashing, doing nothing to prevent a bigger crashsite. Unless he's the Dovahkiin, his yelling won't stop the cars from slipping off the road.
That video is a total douchebagapalooza and their bandleader is the one filming.
