Rules of The Road ...

After buying the car , since last three weeks am gng home in car and returning ..
and teaching my father and sister how to drive on weekends,

In these days, while coming and gng to karnal through NH1 , G.T.Road ...
I have often been wondering about rules of the road ...
Dont get confused or worried , I know all the written rules .. I am just talking abt the unwritten one's ...

As it happens ..
Everytime i go on that root .. there are more than 3 -4 trucks tilted, may the night before ...
May be the driver was drunk or whatever ...
Small cars badly smashed by some heavy weight vehicle. ...
Dead dogs and other small animals ...
Cars speeding at 120 or kph rushing .. as if they are all very busy and cant spare 5 more mins when it can avoid unnecssary risk to their and others life.
Even the bike riders are not less.. they also driving at more than 100... knowing the risk to their life is more as compared to 4 - wheelers ...

Does such incidences occur in ignorance or thrill (of god knows what ?)
Who is responsible and who bears the pain ?
When will learn out responsibilities ?
When will learn the unwritten rule of the road . . .
Is it when something will occur to us or our dear ones ...
I think its always wiser to learn from mistakes of others ...
