Although I do not condone breaking the speed limit or endangering other road users, I do get frustrated with the speed Nazis, who think it's their right to dictate what speed other drivers travel at on the open road.
If the law allows you to travel at 100km/h on the open highway, you people do not have to spoil everyone's day because you are incapable of travelling faster than 75km/h.
If the law says we can drive at 100km/h, I have the right to do so without you bloody lot deciding something different. However, if you break the speed limit and get pinged for speeding there is no excuse.
I have, on the occasion, been pulled over by the police and asked, "Did you know how fast you were going?" Of course I always do, so I tell the officer it was 112km/h. And when the officer says I'm going to get a ticket, he gets no argument from me. I knew the limit and broke it consciously.
But when the police are simply revenue-gathering and hiding in bushes trying to catch drivers hovering on the limit, I tend to blow a gasket.
