I have noticed one more thing, most of times Karwa drivers first ask where you want to go and if it is a bit near they will refuse to go and if you argue with them on meter, they will simply refuse that my duty is finished and i am going back to station so can't take you to your place but with the same driver if you agree to pay without meter what he asks, he will even take you outside doha. Also indian drivers mostly drive very rough and dont care for giving any sort of indicators when turning or changing lanes and dont care for traffic rules and road safety at all.
