Who wouldn't want one?

Cringely:

My Davis is an all-aluminum two-seater with an 85-horsepower engine. The engine was built in 1946, the plane in 1982, and the whole thing cost under $4,000 at the time, though today I have more than that invested in the instrument panel alone. The plane weighs 625 lbs. empty, 1125 lbs. loaded, has a top speed of 140 miles per hour and can travel about 600 miles on its 24-gallon fuel tank.

Why can't I buy a car like that?

Imagine if we took the basic design parameters of my DA-2A and applied them to a modern automobile. The new design would have to carry two people and luggage, have an empty weight of no more than 625 lbs. and use an 85-horsepower engine. With a loaded weight of 1125 lbs., the car would have a power-to-weight ratio comparable to a Chevy Corvette and be just as quick -- probably even faster than the airplane's 140 mph. Driven only 20 percent over posted speed limits as God intended, the car would easily get 50+ miles per gallon.

Who wouldn't want to buy one?

Let's start a list, shall we?

1. People that don't want to die in a minor accident.
2. People that carry more than themselves and a wallet in their car.
