The TTC would have had a separation between lanes for heavy trucks, and those for lighter vehicles. I wouldn’t want to be on a highway, where semis travel at 85 mph, on all sides of me.

Semis? Try a lot of drivers in general. 85 mph means a lot of them will be doing 90+. I've driven a lot of the 80mph areas in West Texas and even in a well-engineered car, I didn't feel safe because of others around me, especially those with just a few fingers on the steering wheel yapping away on their cell phones.

And then there is the Mexico traffic.

Texans here in the Panhandle run 75 or 80 all the time. I-40 west in New Mexico is 75 mph limit now so most cruise at least 85 .

Wide roads good surface an designs.

Certain areas can tolerate such speeds safely.
