Even if you have every intention to stay within limits they don't work. In the US we have these massive stroads in urban areas posted at 35 mph. When I drive (rarely) I have to constantly monitor my speed. It doesn't feel natural and also takes away from, ya know, paying attention to the road. Aside from my opinion that 35 is way too fast anyways.
At the same time I've seen people complain that roads which are clearly not narrow, are too narrow because they can't barrel down side streets at 50. But at least it forces them to drive slower.

It boggles the mind. We sit in these big cozy chairs that transport us almost anywhere with little to no effort. It's pretty incredible. Yet, the most minor of inconveniences can cause a lot of car brains to absolutely lose it. Driving feels adjacent to addiction to many Americans and if people don't get their fix they go into complete meltdowns.
I think people do find driving stressful, but for the wrong reasons. Sitting a red light? Stressful. Cyclist slowing you down? Stressful. Too many other people are using cars at the same time you are? Stressful. It's stress originating from believing you had the god given right to drive like a maniac at all times.
In every part of US cities pedestrian walkways have to cross roads. But really roads should have to cross the walkways. Instead of sidewalks dipping down into four lane highways, roads should have to go up and over sidewalks at intersections. In Amsterdam there was huge expansive brick walkways that cars can use, but they're the foreign entity. Not the pedestrians.
Speed limit signs don't work. People will drive at whatever speed feels right and this is usually way above 20mph. What works is narrowing the roads. When the carriage way is barely wider than your vehicle it magically makes 20mph feel appropriate and 30mph seem fast (which it is). This has the bonus effect that larger vehicles feel it more, which is perfect considering they are the most dangerous and should be driven by trained professionals who are used to such tight spaces.
It essentially makes driving much more stressful, which is exactly what it should be. The problem at the moment is drivers get everything: big, wide, smooth roads, with the best drainage and grading; the easiest and most convenient mode of transport; but none of the responsibility. We need to shift the balance back. You can drive, but it's a big responsibility and if you fuck up the consequences are serious.
