i had this problem over the weekend also, i always sit on cruise control in the country and around town, and then you catch up to slow buggers, and you have to use your foot, its a pain in the arse, your leg gets so tired country driving behind some slow bugger
a landrover was hooning along, and then would slow right down, then hoon along, and slow down, and bend in the road, oh i better slow down, staright, i better munch the go pedal
another one, i was cruising along at 110, and a VS was behind me, would munch it going down hills, and be right up my arse, and then slow down on the straight.. what an idiot, tho the only way to catch the ford was to much it down the hill :D
trailers, and caravans are the worst mongrels... they have to go slow, but atleast pull to the side of the road and let people over take.
theres nothing scarier than overtaking people tho, esp when you go for a big 4 car overtake, you dump it into 2nd, run 2nd to revline (about 140) 3rd kicks in, and you run that to about 160, just to overtake the slow buggers, if your caught (due to the slow wankers) by the cops, thats a loss of license, or a 6 point $350 fine
