You need to gently rock the car back and forth to get it out of the snow. Reverse, brake, drive, brake, reverse, brake, drive... Letting your tires spin faster and faster only makes it worse!!!! Dammit! Sitting in my studio hearing person after person spin their wheels outside, trying to get out of their parking spots. This is why people hate the snow. The snow is our friend. And you're an idiot. That's all.
