Driving!PSVs' special driving schools?

Perhaps one of the most important unwritten rules one must never forget once out of a driving school maybe, "give way to Big vehicles...." this rule would never make sense to you if you are as tough headed as i am, until you meet the daredevil drivers in Tamil Nadu or Kerala(these are states in the southern part of India)
there are some that have been billed as "point to point"(if you've ever traveled between Salem and Erode then you know what am saying)These are passenger buses that would make the matatus(the PSV's in Kenya) back home cringe in shame.They play loud music,are DVD coaches(they show these in the bus possibly so that passengers don't realize how fast the bus actually is)and are driven so fast, they are actually Kings of the road,all they need to do is hoot and flash their lights and if you are wise, you will leave the road and give them right of way.Mind you, the roads are narrow and in Kerala its actually going up the mountain which means blind corners too and the drivers will keep at it without reducing the speed.
Its a little wonder therefore that all big vehicles here have that sign at the back "sound horn Ok". All you need is a working horn system and working brakes and a willingness to overlook the fault of the other driver, especially if he is driving on the wrong side(your Side)of the road, otherwise, you will suffer.
Thought this was a South Indian phenomenon till i went up north and Voila!meet the blueline buses, the so called Haryana Roadways...they have been billed "Mango shake"because they shake you up so bad but they get you where you headed, safely or unsafely,nevertheless.
Amazingly, these guys behave the same way which brings me to the question?is there a driving school specially meant for public service vehicles?because in all the countries i have gone to(they are not many), these guys behave in the same reckless manner, drive at high speeds,flaunt rules and have no regard for other road users.they are solely responsible for the many deaths due to Road carnage and it is a universal thing.
Next time you pass by a driving school, don't leave without those special instructions lest you be rudely reminded that the road does have its owners and it sure is not you.....be careful now....
see you on the other side....
