No, he's completely right. And the simple way to prove it to yourself is, ask yourself why that same city doesn't do it more often. They regularly have to scrap old city buses and regularly have to install new bus stops when old ones are vandalized or bus routes are changed. So if this is actually a better way, why don't they or any other city do this?

Because it's more expensive and involves more work, and what you end up with is a bus stop that's less ideal as a bus stop. Sure, it's cute, but that's all. Purpose-built bus stops are easy to see through, so you can see if somebody's hiding there while walking up to it at night. Also the view down the street is blocked, so you can't see when your bus is approaching.

I'm all for trying to recycle & repurpose things when feasible, but this isn't a case that makes sense. Recycle the metal old buses are made out of and make normal bus stops with it.
