I read in The Sunday Times yesterday that someone has come up with an amphibious car with a top speed of 100mph on land and 30mph on water. Apparently, it has retractable wheels and a jet unit at the rear provides propulsion in water. It must be a pretty limited market for such a vehicle, which - along with the expensive engineering - will make it pricey. The article talks about rich people living in the Florida Keys. Good luck to the team who've spent seven years developing the vehicle, but I can't help thinking the engineering compromises and potential problems make any boat-car a novelty item liable to ridicule (unless we're talking about the Lotus Esprit in The Spy Who Loved Me). Still, there are plenty of people with enough money to spend on vulgar statements like the Hummer H2, so maybe there'll be those who will like to show-off with a boat-car.
