> Unless your goal is to increase ticket revenue or appease the "think of the children crowd" there's no point to lowering speed limits. It doesn't do much to affect traffic speed. To do that you have to modify the road or do something to change the traffic flow.

It’s very simple, put speed cameras on every corner, and fine in terms of day wages. E.g., one week of your income as fine for going x% above.

Several countries are doing parts of this already, or moving towards it.
