The  has released this CCTV video of a hit and run on a overpass. A biker in the appropriate right lane was obviously slower than motor vehicle traffic, causing cars to go around him. 

No big deal until one psycho actually accelerates into the biker, knocking him down. Worse, the driver tries to quickly escape. Luckily, the bus driver not far ahead saw the whole scene and blocked the escaping perpetrator for police to pick up.
