The problem with fines and fees is that it puts a price on things, which is why those electric signs work so much better than speeding cameras.
Sure, a $100, $200, or more ticket is expensive and a lot of money to some people it allows the people who can afford it to easily rationalize the behavior.
"It's only $200 bucks it's clearly not that big of an issue, if it was a real danger it would be more expensive"
However the speed blinkers let you know you're doing something wrong and these condition you to feel guilty therefore slowing down.
