It seems counterintuitive, but it’s a formula Americans should love: Raise speed limits, make roads safer.
Interesting read on how speed limits are set. I’d also point out that people perceive driving faster as more dangerous so a couple factors of faster speed limits could also come into play:
- Better focus when on highways (e.g. No cell phone use.)
- Slower drivers avoiding faster highways when not needed.
I’m a fan all around of faster speed limits.
