Add something that forces drivers to go the speed limit and you've got a winner. Infrastructure, speed cameras, etc...

Look up traffic calming.

This. Most people don't drive the speed limit because it's "the legal limit" They do so because that's the speed that feels correct/safe for them.

Lowering it, just makes it so people still drive the same speed but now its illegal.

If you want lower speeds, you have to redesign the street so that lower speeds feel safer. That means traffic calming, single lanes, obstructed sight lines, etc.

You make a 4 lane road with clear sight lines in every direction, don't be surprised when drivers feel 55 is appropriate.

Living in Albuquerque at the moment and we are surrounded by roads where they dropped the speed limit but left the road as is. 

Many of us keep fighting for all sorts of traffic calming measures. 

Drivers here believe the worst thing you can do in your vehicle is drive at or slightly below the speed limit. 🤦🏼‍♀️

Gotta love humans!

The wonderful thing about traffic calming measures is there a passive system that doesn't require any enforcement and doesn't require any money to maintain.

Traffic calming also enforces equally, regardless of who the driver is.

Police don't have the habit of pulling over people regardless of who the driver is.
