Try visiting Brisbane, Australia. Its fleet of busses are all air-conditioned and run on natural gas. There are dedicated bus-ways [1] and a bridge to the university that only busses, cyclists and pedestrians are allowed to use [2]. Brisbane is one of the most spread out cities in the world, but its bus network and smaller rail system make for a decent public transport system.
