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.

'plays' not played, but yeah, there's probably a butt-load of female grannies who play the drums in the U.S., -There were a handful of all-female Jazz Band in the 30s-40s but their drummers were to young to have been grannies...OR perhaps too gay to want any offspring-Here's one of the hippest on film, Viola Smith....Maybe this was Vega's Granny??


MY GAWD, Frances Carroll (bandleader)....what a LOOKER!

*nibbles on brim of felt coxwain's...

All Hail, Jacob Savetnick (Jan Savitt) of Shumsk, *Russian bandleader and as manic as they come, that score rocks for blocks!

Haha! It's funny because my bandleader calls it "pizzataco".

Bob Wills hated the hillbilly image associated with country music. But then, this was a different kind of country music anyway. If he hadn't played a fiddle, no one would have connected country to the Playboys' music at all. It was really jazz; jazz that portrayed a dignified South, with flowing fiddles and classy, sometimes brassy, arrangements. Their rags, breakdowns, Dixieland tunes, and swingin' blues were an uplifting beacon of light in otherwise hard, depressed times of the 1930s.

The Playboys usually appeared in cowboy dress attire. No sequins or overalls, this was a sophisticated outfit. Bob's look was that of a well-dressed bandleader, but one from Texas. His cowboy hat, cigar, and fiddle were all part of his trademark appearance.

'Bob was a stylish, western rogue,' says Ray Benson, leader of Asleep At The Wheel, Western Swinging Bob Wills disciples for the past quarter century. 'He danced onstage, he was outrageous. He strutted like a peacock, unheard of back in those days.' In all other respects, he led a Big Band just like Tommy Dorsey, in a presentation that was downright orchestral - except Bob conducted with a fiddle bow.
