A little insight goes a long way
[*]taking note of the speed limit traffic signs
So the N1 construction works in Pretoria between the N4 interchange and Zambesi were recently completed and the speed limit was changed from 80 to the normal 120 and yet you still have the majority of people braking hard for the 2 cameras on that stretch of road due to not paying attention to the new speed limit. Extremely annoying.
The braking hard also means that they were going above the 80 that they thought was the limit anyway, so I don't think that people speed by mistake - they know full well what they're up to.
