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.
