Totally agree with the above. I regularly travel with 5 tier cakes assembled with no problems, but a 4 hour drive is still a long haul with a cake. My only other suggestion would be to make sure the customer knew they would need a flat surface to sit the cake on (not the back seat or Grandma’s lap) and provide them with a small piece of grippy shelf liner to keep the cake from sliding around in the car.
