Why do you think speed limits were introduced in the first place

Problem is ma t of those limits were set for cars with horrible bias-ply tires and drum brakes. In modern cars that can easily traverse those roads at 20 or 30mph over they feel assinine.

I would be totally fine fine with speed limits being actual, enforced, no wiggle room limits, IF the actual limits were reasonable in the first place. This would mean most interstates outside of built up areas being posted at 80-90mph, say .
