Riding between 18 and 19's reasonably short too. Plus you get to ride on all of the nice roads around Bath =)

I commute pretty frequently between Melksham and Bristol on the motorway, but my advice is the same as above; shoulder checks are absolute life savers on the motorway! Especially if the guy who was just behind you decides to try his luck and go for a cheeky overtake as you're indicating to change lane.
