Adelaide in the Australian state of South Australia has a curious form of public transport known as the O-Bahn. It is a guided busway. Special buses operate between Tea Tree Plaza in the north of Adelaide and can cover the 12 kilometres to the city in 15 minutes, travelling at 100 km/h. The buses are guided along the track without the driver having to steer.
Around four cars a year get stuck on the O-Bahn after entering by mistake, in spite of there being plenty of signage. One feature of the O-Bahn is a sump ripper, which rips the sump of car when run over and hopefully stops the car when the oil runs out from the engine. While that may sound extreme, a head on collision with a bus travelling at 100 km/h could be catastrophic.
Yep, it really looks like a road for cars to drive on to me. Photos from the electric newspapers.
