Car goes sideways?

Remember that the driveshaft spins counterclockwise ( viewed from the back) and tries to lift the right tire. The sure grip clutches lock in and since the left tire is not spinning yet, it has more traction. This upsets the balance of the car and since the right tire (which is spinning) it is easier to drag it sideways. This all takes place in a split second and the if you are able to get both tires spinning, the back end always seems to want to go to the low side.
