What are they trying to prove?

Often I see at the traffic signals that few two wheeler riders are in too hurry as soon as the signal goes green. I dont understand what they are trying to prove, the vehicles are in a criss cross arrangement at signals in India and amidst this if one tries to rush through he may get smashed sometime for sure.Trust me its even scary to watch these misdeeds on the road.

More than often I see this and shudder at the thought what if something happens right here.
