More on Toyota's 'personal mobility vehicles' - Smartmobs writes that:
Toyota is planning to roll out the latest in its “personal mobility” vehicles at the 2007 Toyota Auto Show. The new RiN Concept monitors the driver’s mood and takes steps to keep it even-keel. It accomplishes this through seats designed to maintain good back posture, an oxygen-level conditioner, and a pinpoint humidifier.
