An angry Chinese father bashed and crashed his Mercedes S-class into his son's BMW Z4 in the middle of traffic last month in Ma’anshan City. The whole thing was captured on traffic cameras.
I can't tell you why exactly the father in his S350 started to play bumper cars with his son's Z4, but I can tell you that they went on bashing each other for three or four minutes. The Mercedes eventually delivered the crushing blow to the Z4's passenger side.
The son then got out of his car and made a run for it, quickly chased by his dad with his belt in his hand.
At the very least, the father and son successfully avoided hitting any other cars, and while I can't find record of the police making any arrests, the damages are estimated at around one million Yuan, or $163,000.
