Can’t recall where I last saw it, but many larger roads are designed for speeds up to twice the posted rate without significant increases in accidents.

Now granted, a big problem in Canada is driver training and vehicle condition, but if Germany can have autobahns with no speed limits, why can’t we? All it would take is a decade or so of gradual re-authenticating skill levels, and a significant inspection system for vehicles. But that’s the trade-off needed if you want to have safe roads at any speed.

Note: for training, it would include extensive mandatory training, pass/fail limits that are far more stringent than what we currently have, and include new driver behavioural features like two lanes pulling apart when a traffic jam occurs, so that emergency vehicles have unrestricted passage – with no non-emergency vehicles using that “shortcut”. For vehicle inspections it would be a level that demands showroom-pristine condition for all vehicles: no visible rust, no nonfunctional parts (even superfluous ones like AC), and the ability to take hydraulic rams to different body parts (underside, body panels, etc.) without the ram punching through due to rust-weakened panels.

This would absolutely trigger the “muh freedumb” people, but you cannot have higher speeds without more stringent safety measures in place.

Most of these speed cameras are being put on city streets, not on highways/freeways where pedestrians basically don’t exist. Also good luck passing a no visible rust law without banning road salt.
