Guide rails, safety nets and bubble wrap are probably the main contributing factor of the general stupidity we see today. Everybody is constrained within these systems that make it so that the most minimal amount of brain power is required to adequately function within them. Lines of the road, stop signs, traffic lights, speed limits. Anybody is a brain on their shoulders can approach an intersection that does not have any sign or light, and navigate through it. Every time the power goes out this is evident.
Speed limits might be a necessary evil but 35 on a back road with no houses is ridiculous. 65 on a highway at 4 AM is unnecessary.
The point being, instead of people needing to actually consider "is my speed appropriate - is this intersection clear - am I too far left of center?" they simply live within the lines, rarely or never testing the boundaries except maybe for a quick rush in their youth.
This concept is everywhere in our society. Almost no thought is required to function. People live on muscle memory and reactions.
Same thing here but it's roughly 107 KMH and called a highway.
The noise and traffic would be horrible and suburban property taxes would be higher than Hunter Biden when downtown turns into mostly surface parking for all the cars. Downtown is the most valuable land in a city, it should be full of bigger buildings that pay enough taxes so that you can enjoy all the city services dozens of miles away from the city without paying too much for it.
We call it 'the line' out here but until recently no road around here had one.
