Cleaning up car wrecks.

Anyone know a good way of cleaning up car wrecks?
Its needed for my RC Arena map, all these wrecks, of defeated vehicles, will clog up, and cause either desynch or lagg, or a crash, sooner or later.

I tried DELETE_ITEM, but it didnt seem to work. It WONT delete the wrecks, not even after a time, or when out of ANY player's sight.

Also tried to let the cars drive to water... but they wont drive!(yes i DID add a driver)
The commands i tried of that, was one with CHAR_OBJECTIVE, and something else.
When i add a driver i make them created immediatly in car, after the player loses control of it. Since peds cant enter MINI_CARS.

Anyone know a solution? And the players use RC cars with weapons to fight eachother, if that info helps.

Try teleporting them into another area or something..lets the map freshen up a bit.

The only teleport command is to warp a player fro ma car to a place, and it desynch multiplayer.

I want a way to clean them up WITHOUT desynch, teleportation, ect.
If someone knows a command what makes them drive, with either arrows, or plain going to water(made water in edges).

I think ill post a picture of the ground floor of the arena, maybe that helps... :/

Maybe "mission cleanup" command would help... But I've never used it...

I never made a mission lol, even if the command is simple. i did never see mission cars just disappear.

Do you know a powerfull command, or a few, to FORCE a char to drive to somewhere, even on field, pavement, or just road?
Since i need something to clean up the wrecks. Other idea's are welcome too.

Hmmm... too lazy to make screenshot, maybe later... lol.
But the arena has arrows, leading to water, if that info helps.
And ill try the cleanup, if it works.

I have two good ideas about this:
1. Crusher Cranes! Make sure the conveyer belts are ABOVE anything reachable.
2. Something that pushes everything off of the edge of the track and into the water, such as a piston that pushes everything in its path every 60 seconds!

Ah... Cranes... Now why didnt i think of that.
Perhaps i can revive my RC Arena if this idea works. Might need minor ajustments to place cranes to reach everywhere.
Else a slow moving conveyor towards water.

Thanks for the usefull idea, hehe.
Seems unlike desynch will happen if vehicles get destroyed, by water, destroyer, or crane.
