The most difficult thing about the supercar driving experiences at Oxotic might be the first thing drivers do: actually choosing a ride. he company keeps its fleet of uber rare $300,000 supercars. Once drivers make their selection, though, it's a straight shot to the open road. Each experience begins with a brief orientation, during which instructors explain how every doodad in the car works so drivers don't hit the wrong button and accidentally shoot silly string from the exhaust pipe. The driving experiences themselves range from five to 100 miles in length, and souvenirs?such as high-def video recordings of rides?keep adrenalin rushes going long after the pistons stop pumping.
