Nasty weather like what the US is seeing has occurred before. I got caught one year, back in 1976 or 77 February, going through Wyoming and on my way down to Florida, going down through the Dakotas, Nebraska, Kansas, Arkansas and into the southern states to get there. Big wind blown snow dunes locked up traffic on the I-80, the major interstate highway and it took a while for it to clear. When it finally did, people's vehicles left big snow dunes on the south side of where their cars were stuck. The roads were iced over everywhere. And worse, I got a flat tire at one point and had to change it myself, in the middle of the highway. That was a bad winter to be travelling across country.
