Mine is when I'm held up in an 100 zone driving by someone doing 80kms/hr and then they come into a 60 or 40 zone & keep doing 80k while I slow down to the speed limit & people try & run over the top of me..[}:)][}:)]
OR yesterday there was a line of holiday traffic doing 70 in a 100 zone..they get to an overtaking zone & speed up to 110kms so you cant pass them & then at the top of the hill they are back to 70kms...@##!!![}:)][}:)]
