Many civic planners will see a video like this and say “that’s not possible” even while watching it happen.

They have no appetite for anything new and they have no appetite for not being the one who thought of it.

They often work under a different set of political or administrative constraints that make these things impossible to execute. Seeing it done on one stretch of road is entirely different than allocating 100 miles worth of repaving budget to a 5 mile stretch to avoid inconvenience. That's a tough sell.

And they do do things when it’s warranted, like the bridge replacements where they build a whole new bridge next to the existing one and swap it overnight.
