Speed limit is enforced by road design, not by signs
I think its by fines actually… Just got a $609 USD speeding fine… I speed less since then
Intuitive system suggesting correct behaviour is more effective than system encouraging to break law and them punishing for it severely
If a pilot repeatedly ignored their equipment and flew too low over populated areas, they’d lose their license in a hurry. When you pilot large, deadly equipment out in public, that comes with the burden of complying with all regulations, whether they feel necessary or not. If the general public thumbs their nose at this idea, that just underscores that it was a mistake to let pretty much anyone drive whatever they can afford however they want unless a cop is looking. We have to reverse that mistake instead of tinkering around the edges to occasionally slow people down by a tiny bit until they get used to handling even your traffic-calmed section of roadway at high speeds.
Well, that is a lot of money (for me and presumably you), but without proportional (to assets) fining it makes laws pay per use. In otherwords, money is not a good judge of character; people can have disposable income and ignore the same fine that changed your mind about speeding. And as another commentor said, preventing is better than punishment.
Context is 20 mph steets, making them more complicated and narrower forces drivers to slow down to not hit anything. Straight and wide streets allow drivers to speed as they feel comfortable.
Motorways on the other hand encourage to speed with wide lines, long view distance, long turn radiuses, hard shoulder and long paint stips
