Ugh . Finally , with him pushing and me steering , we got it out . Then I backed it down and got to fly up the hill ( which is the only way to do it w / out 4 wheel drive ) . That was kinda fun .

Question: Why does backing up then speeding out a hill help one without four wheel drive ?
Answer: The car has more space to use the front or rear wheels to accelerateThe car is able to build up momentum to scale a hill or mud or some surface which is slowing the car downNone of the above choices .The rear or front wheels can then grip on the surface
