I would add the Antrim Coast Road (A2) from Larne to Portrush in Northern Ireland - comparable with the Great Ocean Road in Victoria, Australia. Stunning scenery, views across to Islay, wonderful villages with beautiful names, Ballygalley, Glenarm, Carnlough, Waterfoot and Cushendall. A stop off at the Carrick-a-Rede rope bridge, the Giant's Causeway and the Bushmills Distillery, the world's oldest licensed whiskey distillery, and past Dunluce Castle to Portrush.
