It has not really been addressed much in video, or if it has, I just don't remember. In the video (We Caught Him!) 24 HR Stakeout Outside Hi5 Studios!, there is a point when Matt drives the van around the building twice. If you look closely there is a parked car the 1st time Matt drives by, but it is gone the 2nd time. Not sure if it was just a BTS mistake, but have always been curious.
