Small update to rules (hopefully the last one):
Destroyed vehicle can be now towed/pushed:
You can "tow"/"push" destroyed vehicles by attaching at least 5 meter rope between the vehicles. After that both drivers can drive their vehicles as long as the rope is attached. While towing you cannot exceed walking speed and you must make sure there are no players near the towed vehicles. You can only "tow"/"push" single vehicle at a time.
