What Causes Traffic Congestion?

My observation on What causes Traffic Congestion

1: Mentally Deranged and Selfish drivers who likes to change lane in the middle of a mother of all traffic jam.

This type of drivers get a psychotic high when they are able to quickly slip in front of another vehicle in an already badly packed jam just so that they can be 1 car in front but yet is still stuck in the same jam. (ok, so they are in a different lane.)

Mentally deranged, because this personality type always think that "they" and "they" alone is on a hectic schedule while the rest of us in the same jam is in it for the fun. Ergo they must change lane in order to, in their severely limited cognitive operation, be 1 or 2 miserable cars ahead to have the childish and deranged satisfaction that they are actually moving ahead faster than the rest.

What this delusional individual(s) is unable to process in their limited basic cognitive processes is that by doing so they are not only not moving ahead any faster on the other hand they created a"ripple-effect" or cascading failure that causes sustained traffic jam to the rest of the motorist at the back. (as opposed to heavy but smooth traffic flow..)

How so? Simple arithmetic. An idiot slip into another lane in front of another motorist who will naturally need to brake so that he/she don't bang into the idiot. Possibly 5 seconds is all it takes.

But the motorist at the back of this motorist who don't want to bang the idiot will also have to step on the brakes this time for maybe another 6-7 seconds and it ripples down until the point when everyone will not be moving anymore.. and all this for 1 single idiot!

And therein lies the problem because in KL we have plenty of them "idiots" on the road !
