The Motor MythBusters test the dangerous myth that trailer sway can be corrected by accelerating. Bisi, Faye and Tory add remote control to a truck, load up a trailer, initiate sway and find out if a sudden boost of speed will stop a trailer fishtailing.

In true hot rod fashion, the team tests the myth that chopping the top of a vehicle will make it go faster. They buy a '70s Dodge van, cut out 12 inches from the roofline down, and then see if that modification gives it more speed on a quarter-mile track.
