President Lyndon B. Johnson, a practical joker, owned an Amphicar … an automobile that could float on water and be piloted like a boat. He loved to take guests for a ride around his Texas ranch then drive headlong into a lake. While his guests screamed and white-knuckled the dashboard, Johnson would shout about faulty brakes. The joke was on the unwitting victims. Johnson was one of the few proponents of the Amphicar, which was manufactured from 1961 to 1968 in West Germany. Demand for amphibious cars was limited. The Amphicar was discontinued, and the concept was relocated to Hollywood spy flicks and superhero movies.
