Taxis are OK. But the drivers are mostly unaware of the locations in NCR. Some of them are not aware of Parliament Street, India Gate and other similar well-known places. As a result they use the GPS. But the GPS systems at times gives wrong directions. I have personally suffered on several occasions. As a result there is wastage of time and also higher fares. Any driver who is hired by the companies must train them for few days about the locations of important places and their routes in the NCR.
