Directions

Just printed off directions from Abersoch (mum's caravan) to Gid and Suzi's. The directions consist of 6 A roads. Why then, do I have 4 pages of A4 which basically tells me the same as "Take the A497, then the A487, get on the A470 and stay there until you hit the A483, then take the A40, then the A4069"? The RAC seem to delight in wasting paper by telling me things like "take the 3rd exit at the roundabout into A470" about 20 times. I *know* it's the A470, you don't need to keep telling me to stay on the same frigging road!
