Wow TS typical asshole idiot driver.

Although the van driver was a little drama queen coming out of his vehicle (LOL for a sec I thought he was namewee anyone think so)
But the lane he was turning into HAS NO TRAFFIC AT ALL.

The direction you are heading is totally jammed up, yet you had to move your car into the yellow box.
The result is van cannot turn right into his way, and his vehicle will block EVEN MORE cars behind him, worsening the traffic situation.

Conclusion, OP really go learn some common sense maybe go learn undang again because clearly you bought your license.
