As suggested just above, if you’re driving clockwise, south, then west, then north, then east, then south, the passenger will have the views out to sea on their side of the car. The driver, frankly, will be so focused on driving (keeping to the left of the centerline, not going so far to the left that you go off the road or into a stone wall, minding the speed in Kilometers Per Hour, dealing with oncoming traffic) that admiring the scenery while moving will be difficult (and potentially dangerous). Driving counterclockwise, so the driver has the sea views out their side of the car, won’t help the driver too much, and blocks the best views for the passenger, a lose/lose proposition.
Our last two trips, one in the north half of Ireland, and one in the south half, were both clockwise. Allow plenty of time for stops, so that both of you can get out and enjoy the scenery, viewing out to sea and also inland.
