Who are we to argue with a "grown-up golf cart?" The Rinspeed BamBoo ($TBA) is aimed squarely at the picnic/beach crowd, featuring a German-made 54-kW electric motor good for speeds of up to 75 miles per hour and a battery with 65 miles of range, an onboard foldable bike, a two-piece waterproof design, a communication display in place of the radiator grille, an inflatable roof that doubles as a beach blanket, a key hidden inside a Swiss Army Knife, 17-inch AEZ three-spoke billet aluminum wheels, and an included seven-inch tablet computer. Crazy? Perhaps. Cool? Definitely.
