I'm sure Giddy will jump in on this thread soon.

Yes what you were doing was in the eyes of the law illegal. You were still in a 60 zone doing 79, which is what the police gun must have seen and in their eyes you were still in a 60 zone. I can see your point though, especially if you have to speed up to merge with traffic entering a freeway.

From your description the cops were out to get someone speeding by the placement of their car right on the speed zone boundary. I personally have nearly been done like that as well. It really depends on the mood and the cops in question.

SPEED TRAP alright. C*&t of a thing. Easy prey for the cops. Surely they have something better to do that contributes to road safety ???
