Poor Lane driving practices, especially by autos, taxis and large commercial vehicles, not curbed; parking and stopping on crossings/ turnings, wrong side driving, pedestrians crossing when traffic light are green, no mobile patrols, No traffic cops at peak hours (except for VIP visits) but multiple cops at one crossing during daytime, allowing vehicles to cut in from left at narrow flyovers (RTR, Dwarka) . Its like rocket science!!
