Getting stuck in a traffic jam can be one of the most frustrating parts of travelling around a busy city.
Now engineers in China have come up with a radical way to overcome the problem of getting around in traffic.
The country's Transit Elevated Bus (TEB) has taken its first test drive.
The 22-meter-long, 7.8-meter-wide and 4.8-meter-high TEB-1 can carry up to 300 passengers over the top of cars and let traffic pass underneath it.
This week, it underwent its first road test in north China's Hebei Province.
The test in Qinhuangdao City, evaluated the braking system, drag and power consumption, according to tebtech, a company that helped build the TEB.
The TEB has already attracted interest from governments in Brazil, France, India and Indonesia, it has been claimed.

In the cities where l have lived which have trams, there is always some git who positions his vehicle on the tram lines believing that he is 1 invisible 2 immortal 3 beyond the law. I work in China. I am convinced the same will happen here. Sorry but true

What could possibly go wrong with such a great idea.

There needs to be a barrier such as on motorways, so that if vehicles clip the wheel mechanisms that they simply are nudged off. I don't expect speed to be a real concern for either the bus or cars, as it will be used to beat congestion in urban areas. It could possibly work.???
