You probably saw the video on Monday of several vehicles slipping and sliding on Beaver Hall Hill on a snowy day.
About 20 million other people around the world did, too — a little over 24 hours since it was first posted to Facebook.
But what did it feel like to be right there, in one of the cars that was involved in the multi-vehicle pileup?
Pietro Mucci, a tailor who often does business on Beaver Hall, was in his Lincoln Town and Country van at the bottom of the pileup, and was hit by the first bus seen in the video. Like all the other cars on that hill, he had trouble manoevering on the slippery road, but didn't hit anything and managed to turn his wheels to the right after he came to a stop.
Then, everything came crashing down on him — literally.
"After a few seconds, I saw the massive bus coming on me. I held on to my steering wheel and hoped for the best, my friend," Mucci told CJAD 800's Andrew Carter. "I couldn't go, because there were three cars in front of me that were blocked. I got hit once by the bus, after the truck hit the bus, the bus hit me again. After the other bus, we were hit again. After the other bus I got hit four, five times, one after the other."
Aside from the two STM buses, a pickup truck, a police car, and a snowplow — ironically, which was spreading road salt — came crashing into the pile.
No one was hurt, in the end — but the repeated hits left Mucci's van seriously damaged.
"All the back is all smashed. And the front bumper...got bent in a bit more," he says. "The insurance company...I'm going in for an estimate today."
Meanwhile, CJAD 800's traffic expert Rick Leckner says the salt spreader seen in the video should not have been sent to send salt on the hill.
"You don't send a truck like that to do a hill like Beaver Hall Hill," Leckner says.
He points out after just about every snowfall, hills are slippery in Montreal — but somehow Westmount, a city with lots of steep ones, doesn't seem to have very many problems at all.
"Why does Westmount do it so well?" Leckner complained. "You cross the border at Atwater, you're going from a third-world country into modern day."
He says the city needs to implement standard operating procedures to keep this kind of thing from happening again.
"This is Montreal. This is not Miami. We have to deal with this in a very pro-active manner...and somebody's heads should roll after this. And what really got me is yesterday, a spokesperson for the city said, 'yeah, it was bad, but this could happen again'. Are you kidding me? Why?"
The video even caught the attention of American late-night host — and next year's Oscar host — Jimmy Kimmel, who said the pileup was "like curling with cars".
