Only people like you will accerlate more. Slow moving traffic
accerlate hard for what? Close gap ya, but you rather crash into
somebody ass or maintain safety distance. People wanna cut into
your lane, let them cut lah. 
True. If the traffic is that bad, the car which cut in front of
you won't be reaching his destination any earlier; you won't be
reaching yours any later. Both of you are still stuck in the
jam.
Today's traffic seems bad, PIE, ECP, KPE, jammed!
