Higher speed limits are coming. But the case against them isn’t based on road safety alone – claims of increased economic efficiency are not supported by the evidence, either.
The limit should be the enforceable and safe speed for the road, the road design should reflect the desired speedlimit.
My area recently built highway bypasses around town. One section is built exactly like a freeway but they slapped a 60 km/h sign on it. Nobody does 60 km/h because the road feels like, and is designed for, 100 km/h. This is the wrong way to do it. If a road is a 60 km/h zone, the lanes should be more narrow and the banking on the turns should not allow average drivers to feel safe at 120 km/h.
And road design factors into the average driver’s speed far more than a sign with with a number on it

I think you’re thinking about this backwards. Instead of ripping up and replacing the ENTIRE ROAD, just replace the 60 km/h sign with a 100 km/h sign.
