Product development...
Product development chief at GM, Bob Lutz, revealed at the Detroit Motor Show he"s already worked out what drivers will do when their hydrogen-powered car is running low on juice. He told Auto Express: "When they are getting low on hydrogen, motorists will simply hit the "fuel" button on the sat-nav screen and it will give them directions to the nearest filling station. It"s the only sane way of getting the car topped up."
