I happen to have the same issue regarding the "Police Car in Aisha's House during the Laundry Day cutscene", but I have another issue, which amusingly enough is also in a cutscene set in Aisha's House.
In the opening cutscene for the mission "Bleeding Out", there's a second Johnny Gat who...just stands there. I have attached my loose.txt and cutscene_patch.ini for you to take a look at.
EDIT: Nevermind, using the patch for the cop car problem also removed the impostor Gat.
