Typically no.Say you only have your car in your name and you get a R100 fine that you don't pay... What they gonna confiscate? Your R100 000 car?
Speed cameras and their placement are entirely about making money. In Cape Town we're still waiting for them to follow through with the promise of making the cameras visible and only placing them at danger spots.Living in Durban I OFTEN see speed cameras in areas that are NOT high-accident zones, or where they have arbitrarily changed the speed limit down a bit and are now obviously good cash-cows for the municipality.
The problem is that speeding is a red herring. There are other problems that are not soundbite friendly and are going to be difficult to address. Not to mention that they probably won't be profitable.
