Learn Spanish (Latin America): No he visto lo de la zona peatonal. - I have not seen the thing about the pedestrian zone.

The phrase lo de translates to "the thing about" or "the matter concerning." You use it when referring to a situation, event, or topic that both speakers already know about, without having to name a specific noun. Here, it refers to some known news or situation regarding the pedestrian zone.

Why do we use the neutral lo instead of el or la?

We use the neutral lo because we are not referring to a specific masculine or feminine noun. Instead, we are referring to an abstract idea or situation. If you used el or la, you would need to include a specific noun to match it, like el problema de la zona peatonal (the problem of the pedestrian zone).

Is it common to use he visto instead of the simple past tense in Latin America?

It depends on the region. The present perfect (he visto) is used to talk about past actions that are still relevant right now (implying you haven't seen it yet). However, in many Latin American countries, speakers often prefer the simple past and would simply say No vi lo de... (I didn't see the thing about...). Both are perfectly correct.
