@Knor: yesterday when I was going towards home after work I faced this situation.. speed limit was 100Kph and one guy in front of me on fast lane was driving at a speed of 70kph what to do now and there was a more space on the right lane then their was a bus I flashed him he didn't move I got closer he didn't move then tell me what to do ??? and one more thing in front of him there was no vehicle within 6km..
and driving slow in fast lane this is also a violation..
