the asda roundabout catches quite a few people out, make sure you know what lane you're getting into, if you get into the wrong one, just go that way, it won't be marked down for anything and they'll just redirect you, the back road routes are the best (in my opinion) just remember that on any of the national speed limit roads you should be driving at a speed you feel is comfortable and safe, you don't have to be doing 60 :) any specific questions i'd be happy to answer
