Except for the WW2-era Schwimmwagen, no other amphibious car has gone into mass production. That might change soon, if Gibbs Technologies can square the circle between US highway regulations and US Coast Guard regulations:
Gibbs Technologies, based in Nuneaton, England, is the only major company now making a serious push into the amphibious car. Its Gibbs Amphibians Inc. division, in Auburn Hills, Mich., has developed the Aquada, a sports car that can hit speeds of more than 100 miles per hour on the road and then, with a press of a button, turn into a boat that can do more than 30 mph.

The reason it is still in dry dock, he says, is a conflict between U.S. government regulations for vehicles on land and on water.
For example, air-bag sensors must be set according to National Highway Traffic Safety Administration standards for the car to be approved for the open road. But on the water, the settings are too sensitive. Waves that crash on the vehicle deploy the air bags. Another problem: An Environmental Protection Agency rule requires a catalyst to control emissions which can heat up several hundred degrees. The Coast Guard bars anything even half that hot operating in the engine compartment.
The Aquada is on the sidelines for now, but Gibbs is moving ahead with a drivable jet ski it calls the Quadski that will be on the market by year-end. With wheels that fold out horizontally when it is afloat, the Quadski can travel as fast as 45 mph on water and on land. And it has fewer regulations to meet because it is classified as a personal watercraft.
Flying cars have shown up closer to the showroom in recent years, but they’re still not available to the general public.
