If you leave a car somewhere that is not covered by radar, the triangle marker disappears from the map. Pretty sure it would persist in 0.11, but I may be wrong.
Anyway, the correct behavior (IMHO) should be that things don't disappear from the map unless it is re-charted and they are discovered indeed not to be there, so you may have a ghost of a long-gone car if it was destroyed while you weren't there, but you can always find where you left it if nothing happened to it.

Thanks for the report. This is now fixed for 0.12.3.
If you want to get ahold of me I'm almost always on Discord.
