First of all, it's incredible density of traffic.
I personally believe that it is very irresponsible of his part, drive this way and moving the car so fast .
It's fun to see the other drivers, some are frozen and slow their vehicles, others are friendly and give way, and others mf, deliberately blocking the passage.
summarizing: it seems that in all countries, you can move faster using the slow track.
A car is a responsibility, power needs control, and all this must be use with wisdom
