With a top speed of about 74 mph, this car won't appeal to everyone. Plus, it looks like it seats just one. But, if the price is right this thing could change urban traffic tremendously.
One commentor on the article suggested they shoot for 150 mpg and allow faster speeds. But, as I say, this may be perfect for the urban areas, and they don't need the speed. They're bumber to bumber anyway.
