Amphicarz!!! Yeah!!!!

[SMIDSY]

you can eat green eggs and ham in it.
it dont need to pass DOT standards cuz it is a vintage car
they all look exactly the same so they all have fins (part of the reason they failed is because by the time they went into production fins had gone out of style)

and that car is way too expencive for the average person.

THAT'S more like it Vulcan...yeah.

The cars shown in the top picture resemble something akin to a toy.  They look unsuitable for anything other than a quick joyride on a dead calm lake or something.

The one you posted actually planes and looks like it could handle some "chop".  I have no doubt that is more expensive than SIMDSY's cars, but at least that one has "utility".
