Maybe if we used binoculars, we could extend our line of sight? I mean by activating the item in menu, then going into a view mode with extended viewing range. At least this way we could see what is about 2 map tiles away from us without having to walk in the zombie hoard that waits there.
This is an alternative to all the work required to make a more detailed map for “zooming in”.
I like the zooming in idea though. Also the named car map markers idea is great too. I myself lost a car once around v0.7
