Changing the curbs requires a drainage redesign.

Does using real metal bollards instead of plastic bollards that might as well be imaginary require a drainage redesign, though?

The short answer is yes.

The longer answer is the redesign for the footings needed and the having to raise grade around the bollards to ensure normal traffic doesn't hit them because they win everytime not the car. And have setbacks from the new curb to ensure someone can open their car doors easily. There is a lot of planning and coordination that occurs between a bunch of city and start agencies and utilities and private stakeholders where the bollards are places

The entire point is that they win every time not the car. And cars win every time not a human being walking.

Paint them orange make them reflective and if people can’t manage to avoid hitting shiny orange things that have a foot or two of painted striped in front of them, then they deserve a fucked up car.

I don't disagree with you. But also there are many factors that go into these decisions. It's not that black and white. Engineers have to consider a lot of city state and federal laws rules and regulations. Such as ADA requirements. Utility interaction (existing and future). How the general public will use and abuse them. Because people are dumb. Engineers often have to thing about how to help the dumbest of us.

Also everytime the bollards get hit they need to be redone. If it's just a surface scratch then no but any kind of hit that can damage a car. Because the integrity of the bollard is compromised and it won't work as designed the next time it gets hit.

Also proper drainage needs to occur around the bollards otherwise water will degrade the metal and they are no longer useful to protect.
