Zihuatanejo and surrounding area safety

Hi — reading through this forum it does seem that there is a pretty significant amount of crime and violence. Is it safe to drive to neighboring areas like Troncones or down near Petatlan? I have traveled throughout Mexico but the stories here are giving me some pause.

In the daytime we drive wherever. That includes trips to Lazzaro, and Puerto Vicente. No issues since December.

But don't drive the highway towards Altamirano....day or night.

WHAT?

WTF would drive there? That is clearly not a main highway.
