Yes ofcoarse, you are right a/c full time on, i'm with my family with two kids so a/c is must.
On my way to Kohat, I drive a bit slow due to road condition... and from Kohat to Peshawar Road is fine and we all especially kids really enjoyed while travelling through Kohat Tunnel. Peshawar roads are also very good. and on my return to rawalpindi via M-1 really enjoyed excellent driving experience all the way and speed is around 130 to 160.
Thanks God that I was escape from Motorway Police bz... when I see them I reduce the speed a bit.. but when I saw that they are busy with their newly catched "Murghay" I once again push the accelator padel and maitained my speed of 130 to 160 throughout the way.
