Concept cars aren't for the general market. They're more like works of art that show us what cars are like when we dream.
Manufacturers let designers and scientists loose, allowing them to make cars that try out new concepts. Whether it's for design (a door that opens upwards, wings) or for scientific purposes (artificial intelligence, zero-emission energy), concept cars are windows into the future.
