It's very strange to complain that cars run red lights, but somehow not stop signs. I expect that if the intersection were as empty as it was when he was filming, you'd easily find people driving at a similar speed regardless of the stop signs too.
I know it as the "California Roll" - to slow down but continue to cruise through stop signs.
In my own country, where stop signs are relatively rare anyway, this behavior is so common that it doesn't even have a name. I think it's much more unexpected here to see anyone truly stop at a stop sign on an empty street than it is to see them slow down and then continue on. And I would bet police would not bat an eye 99% of the time if they saw someone do it.
My experience has been that cars will happily roll through stop signs, but at nowhere near full speed like they're doing here.
