Treehugger about Toyota's continued push for environmentally friendly transportation. The hybrid car manufacturer will be testing a new lower impact, mass transit scheme this March in Japan. The Z-Capsule bus runs on a low-emission, compressed natural gas engine. But to further minimize impact, they will run on an Intelligent Multimode Transport System (ITMS) that will automatically adjust schedules and route based on rider demand. Oh yeah, these things can operate without drivers as well!
