The old duffer that I followed up the A77 from Cairnryan all the way to Girvan yesterday evening, you have probably met the type, as soon as the road bends or twists, they are down to 25-30mph when the bend can safely be taken at 45mph (at least), then when they hit a straight they are off like lightning, on the Glenapp climbing lane section they were doing 75pmh!!! crawled up the rest of the climb at 30 - 40 then off at 70mph plus on the straight over the top followed by a maximum of 30mph down the Smyrton slalom to Ballantrae. Very frustrating!!
