Suppose you have a misaligned intersection, so a car that drives straight through ends up on the sidewalk. This is a bad design because pedestrians get hit by cars.

Suppose you have the same intersection but put bollards on the sidewalk. This is a bad design because drivers hit the bollards and damage their cars.

You want a design where cars go through the intersection without hitting anything.

No. You want an intersection that is safe for everyone outside of cars, and bollards help do that. If drivers aren’t capable of negotiating streets with them, then they shouldn’t be driving, or they should be driving a smaller vehicle. The idea that we should be building our streets to make driving easier is exactly how we’ve ended up with so many people being killed by cars every year in the US. Car centric design is a failed experiment of the last 75 years.

Why would you not want an intersection that is safe for everyone, period?

The size of the vehicle isn't what causes most collisions. Moreover, there are certain roads that have a disproportionate number of collisions. That implies there is something wrong with the road. Roads should be designed for actual reality rather then ideal hypothetical drivers and conditions.

That is not how we've ended up there. It was quite the opposite. We made driving a necessity by moving people to the suburbs, without making roads safe enough that everybody could do it, and then demanded it of them regardless.

It isn't the monkey's fault that the only housing he can afford is 30 miles from his job and he has to take a road full of obstructions to get there. The monkey's behavior is predictable, and we know that what happened last year will happen next year unless we do something different. "Damage the monkey's car" is not a solution, it's just the fast track to angry monkeys.
