Fiat might have found the best way to beat the unbearable Californian traffic congestion, by creating a vehicle that can be driven on water. Actually, the Fiat 500 Personal Watercraft is a modified version of the Cinquecentos, combining a jet ski with the Fiat body on top of it. This was the clever marketing tactic by Fiat, unveiling three unique vehicles at VANS U.S. Open of Suring in Huntington Beach. These surreal amphibious hatchbacks performed tricks at the surfing event, impressing the crowd. Unfortunately, none of the Fiat's is up for sale to the public.
