The Toyota RiN, whatever that stands for, is the world’s biggest car  company’s take on designing the car of choice for the health freak of  the future. 
With a massive greenhouse, seats that keep your spine in its  proper position, an oxygen-level conditioner and humidifier, plus a  meter that gauges your mood through the steering wheel and then displays  a colour based on your psychological state, Toyota thinks it can make  better, happier motorists, that are more aware of nature and the society  that infuses it.The design language is based on the deep-rooted and tall-growing  Yakusugi tree (a variety of Japanese cypress) for its exterior and  interior design to express both “harmony with nature” and “healthy mind  and body”.
