Narrative:

At approximately XX30Z a private vehicle crossed runway 25R from the north ramp and came to a stop just short of runway 25L as a cessna passed just in front of the vehicle, taking off from runway 25L. The vehicle then turned around and crossed runway 25R again and exited the airport on the north side. City operations and phoenix police department chased down the vehicle and gave the driver a warning. The phoenix police department called later and said until the airport gets no trespassing signs posted, they can't do anything. This was a potentially dangerous situation and we should get some kind of signs that stand out and alert unfamiliar airport observers. A vehicle deviation was filed by the controller in charge.
