This game is a parody.
It is definitely, positively and (hopefully) legally, NOT the game Grand Theft Auto Five.
Sure, it's called NotGTAV, but those letters stand for Great Traffic Adventure and the V is silent. Like the one in "lawsuit" (which, you'll notice, is also invisible).
This short tour of the glories of the UK’s M4 corridor is easy to play, hard to master, addictive, very funny, and cheap.
