As part of the LA Auto Show this November, leading automakers were asked to submit ideas for a design challenge.
This year's theme was the "RoboCar of 2057" and the submissions are as far out as that date.
The concepts take into consideration environmental concerns and safety as well as imagination. General Motors based its car on the ant; Mazda has you thinking like a samurai; and Nissan wants to give you a pet that does the grocery shopping.
Check out CNET News.com's gallery that includes photos and concepts from Audi, General Motors, Honda, Mazda, Mercedes-Benz, Nissan, Toyota and Volkswagen.
