As someone who lives in a region that gets a lot of snow, I know that basically any vehicle can get stuck. When you get unlucky, or do something dumb, you can end up in a position where you simply don't have any traction.

But that's the thing, you can usually avoid the situation by not doing something dumb, like driving right up onto the beach. And if you are driving on an unstable surface like sand or snow, accelerate slowly and decisively, don't floor it and then stop or you'll roll back into the rut you just made.
