It's not just in the US. Denmark had a snowstorm about a month ago and it was chaos because people take stupid risks. Large numbers of people drive around on summer tires as well as the majority of both trucks and busses.
If people only put themselves at risk, fine. The issue is when trucks and people who felt compelled to drive on summer tires, in a snowstorm, during covid, block the roads and prevent the remaining population from getting home safely.
