What’s the general opinion about trams on plazas here?

In my opinion, it’s pretty nice. Especially when the trams have a few minutes (here 2-5 min) between them, they can be used to switch sides normally without having to worry to get run over. And adding to that, it still can be used as a normal plaza when there is no tram at the moment.

On the other hand, this will obviously slow down the trams, because people tend to walk in front of it more often and thus, the trams can’t really drive through like normally.

Are there any other ups and downs I’m missing?
