Delhi Metro though very spread but still few ares are not that well connected. For eg South West Delhi including areas of Delhi Cantt, Palam, Dwarka,etc are connected by Blue line but most daily people are office goers to Gurgaon which has no connectivity apart from Dwarka-RajivChowk-Huda which more time taking than taking the Dwarka-GGN old road or NH-8. Thanks to stubborn Haryana Govt who is not willing to pass Dwarka-Iffco metro due to realignment issues(watning old GGN connectivity)
