But we're talking about car location, not encounters, I can remember some TB encounter vs SF caravan that turned into very very very long battle vs some evil polaks (Sir Hubertus and others), who were entering encounter again and again ... and again, we killed them over and over but they returned, then we had no more ammo and died

There was also some random PKer who entered just before combat vs other players and he said that he'll kill us all, as a result he died 1st. They were entering encounter even after 1 hour of it's start, but it was 1 wipe ago, I think now it's not changed and you can find someone in encounter at any time. But not car location and question was about cars.
