In the early patches of GTA V Online, people could SP to MP glitch towtrucks, or duplicate them from other players with a simple join job glitch. The only problem is, they were buggy to the point where they were unusable, so they often froze the game for you and possibly the entire lobby if one were to attach another car to it. But a different outcome would occur if you hooked several towtrucks together, and I remember doing this with a few buddies of mine, and as we started driving, we started levitating and driving in circles at a very fast speed, the hooks of the towtrucks were getting insanely long and we just kept flying up gaining speed and eventually our cameras completely broke and zoomed out insanely, and we all crashed. Still the best thing I ever saw and experienced in GTA Online!
