I got trapped in this chaos trying to get away from Gloucester, I was travelling back from my Father's north of Hereford and wanted to get to Andover, but the timing was just awful as the snow hit the Gloucester area so fast.
My normal route takes me past an area called Birdlip which has a high elevation so can get hit with snow very badly and unfortunately they ended up closing the road (A417), ended up just queueing trying to turn around and head for the M5, that took me a couple of hours only to get stuck on the M5 itself for another 2 hours due to multiple accidents that happened earlier! Some people just cannot drive in snow. What should have be a journey taking me 2.5 hours ended up be just over 6 hours!
I saw some 4x4s struggling when they really shouldn't be, most people just putting their foot down spinning their wheels instead of taking it easy. Was my first time with my Audi + Quattro and was pleasantly surprised how the rear wheels kicked into action the moment any slippage was detected on the front wheels (haldex system).
Kinda want to see those videos you mention though
