I've lived in Michigan most of my life and only people in the remotest places have snow tires. City folk just use the same all-weather radials all year round and maybe keep some chains in the trunk for emergencies.
Honestly, tire tech has come a long way even in the last 10 years. Some current 3 peak rated all seasons can outperform some of yesterdays best snow tires.
Michigan is similar to parts of Canada. All-seasons that are rated for snow are pretty common here too.
Then there is every doofus in a Suburban skidding around like a kid on a 2-ton toboggan rocking summer tires as they tell everyone, "my truck is heavy, it pushes down THROUGH the snow!"
Some people refuse to even buy an all-season even when they know it exists.
