Na na, there is no patch where one can go as high as 150kmph.....well before achieving this speed one can summit nanga parbat without spending $25,000.
3 factors are involved in a joyful drive (a) machine (b) person behind the wheel (c) very well remembered turns, ups & downs on the highway by (b) the person. Those drivers of wagons and buses drive aggressively on KKH because they drive daily and even remember each and every pothole. I have never tried to copy them though I am driving on the highways for the last two decades and have driven on KKH four time already.
