<< I had a similar situation today, but on single carriageway
Im heading back home after a wee jaunt down to Largs, get onto the road (not sure about the name but going between the bypass and Beith) and theres a couple of cars in front doing 50 in a 60, so I thaught "Ill just pass these couple of old codgers with the superior power of Subaru" so when it was clear to pass I engage 3rd gear (best gear for these sort of things) and overtake the first and pull back in as theres a couple of cars coming and to my amazement the old git starts flashing me after I get back in. The same happened after I passed the 2nd old git. (both were driving Rover 75's) Im not sure if its just because I startled them as they were not paying any attention to what was going on arround them or the fact that they do not like being overtaken by us young whipersnapers, but why be pissed off about being overtaken when you are not even doing the speed limit??????? its not as if I made their ears blead with the sound of my exhaust as its still standard.
