Alot of drivers on the road dun bother about bikers, they think
that bikers are like 2nd class road users 
Unless they themselves are bikers too, then they are more
considerate to bikers.
Esp people driving bigger cars really a danger to bikers. If an
lady is the driver worse, I nearly kena accident both on my bike
and car before, but heng I anticipated it and avoided it.
Usually I high beam them , stare at them or horn them like hell.
Dun give face one.
Taxi drivers, I give a little face, sometimes cannot blame them,
times are hard and they need $$$, so they have to snatch passengers
and also driving long hours damn tired one. I drived 14 hours
straight b4, wan lan, can die sia, damn sleepy!
The other ppl to watch out are those construction truck or
container truck drivers. They earn money by per trip, so that's why
they cheong on the rd.
