The problem is that you’re not arguing anything.
No, the problem is that you presented no argument. You just presented a false equivalence.
Your first comment is an ad hominem at best
I quite literally addressed what you wrote, and the complete lack of substance. It wasn’t any kind of personal attack. You’re abusing logical fallacies in order to sidestep the fact that you never presented any kind of argument.
Your actual argument boils down to, “AI isn’t complex enough yet, therefore it will never be or is some long time away”. Okay, that’s really not much of an argument. Progress marches on.

“Traffic bollards” or “flexible bollards” seem to be the terms for this type of bollard. They’re intended to guide traffic, rather than to stop it dead as a security measure.
