The rendered clock icons represent the polygon around the blue car - one of the 3 polygons passed in the request body. For some reason the API doesn’t avoid the polygon in 50% of the usecases

Hey,

the multipolygon you’re passing is misformatted. I assume you want to pass three polygons, but you’re passing one polygon with two inner rings.
You can fix this by encompassing each of your polygons separately with square brackets:

{
   "coordinates" : [[
         [
            [ 20.5089215992338, 44.8137701632598 ],
