There are a multitude of cases where in Women have been molested especially in Metros when they tried to travel alone in the night. In India atleast women cannot safely travel alone in a taxi driven by men in the night. 1. Men taxi drivers drink and drive 2. They have tie ups with highway robbers(Not saying women taxi drivers dont but the probability is less). 3. There are cases of Callcenter Cab drivers raping women for late drop offs.
So as far as India is concerned this is a good move. There is nothing wrong with all Woman taxi drivers as long as men are also allowed to ride into it and pay the regulated fare. Nice Move I would say.
