Don't want to get into the debate about porcine law enforcers and speeding in general. I'm no angel and I've paid my share of fines, ignored even more than I've paid, and got away with it, and even negotiated a couple of on the spot 'discounts'.
I just want to rant about the particular one at Riversdal on the N2. I know perfectly well that the trap is there, and I always drive well below the limit, but it makes no difference. The bastards will issue a ticket even if you get out/ off and push.
Why don't they just come clean and call it a toll 'cos that's what it is.
