It's not about making the roads more narrow or winding per se. It's about deliberately slowing cars down where they need to, through the road design. See this video for example: https://youtu.be/bglWCuCMSWc https://youtu.be/bglWCuCMSWc Besides that, roads in the US are generally poorly classified. They're often trying to both function as both high throughput roads and destination serving streets. Such hybrid roads are known as "stroads" and they're bad for everyone involved. Stroads are bad for moving cars fast due to the many conflict points (driveways, intersections, etc.) that force drivers to constantly slow down. They are also bad at serving destinations because the many conflict points make stroads very dangerous, especially if you're not in a car.
