Are you saying that if you are caught speeding at 10 KH over the speed limit, you would think it fair that your fine should be the same as the one who was fined for going 100 KH over the limit?
No, that wouldn't be fair. But under the current system (at least in Australia) I was once fined for doing 84 in an 80 zone, down a hill on a three lane freeway. The fine was more than $100.00. Do you know how often you have to take your eyes off the road to make sure you don't accidentally do that?
Our current laws allow for revenue raising under the guise of road safety. It means that we have laws that aren't reasonable anymore. The entire legal system is to some extent susceptible to that kind of corruption.
