Bikes are better than cars in snow, however. A fat bike's tires 'float' across the surface of the snow, like snowshoes, and can handle any snow depth. Regular mountain bikes and commuter bikes with knobby tires handle a few inches of snow quite well, because the knobs capture snow between them, and snow sticks to snow. Cars, on the other hand, need a vast expenditure of effort to plow the snow off the road surface, so they don't slide around in a few inches of snow, or get stuck in deeper snow.
Bikes also aren't great for snow, heavy rain, or extreme temperatures.

And then there's the salt, which destroys the cars...
There's no bad weather, only bad clothing
