Designed to promote harmony with nature and evoke a warm, fuzzy feeling inside, the eco-friendly Toyota RiN concept car features heated ergonomic seats, an oxygen level regulator, a spot humidifier, a “mood training” steering control system that monitors the driver’s psychological state, and greenish glass that protects against UV and infrared light while enhancing the natural beauty of the view outside. The exterior design was inspired by Japan’s old-growth Cryptomeria trees known as yakusugi, which are found on Yakushima island, a natural World Heritage Site known for its pristine, ancient forests.
