Drawing priority in maps

I’m creating a visualization for the parking position of my car.

As there are some “common” parking places (home, work and so on) I want to mark them in the map, which is easy enough.
But the layers are changed when zooming in and out (i.e. sometimes the car icon is behind a POI icon, sometimes the POI is behind the car.
Is there a trick to get the car always in front of all other icons?
