Traffic snarls are the main complaint that residents and visitors of Bangalore have. I personally feel one can manage slow moving or heavy traffic but not indiscplined drivers, especially the 2 wheeler riders weaving in and out of lanes.
One of my colleagues was in M$ Hyderabad, had this incident to narrate and it beats most other bad driving examples:
Some motorist, while driving put on his right indicator but continued going straight ahead. Actually he did not stop till the next trafic signal, where a fellow motorist asked why he hadn't turned right though he was indicating he would. The first motorist replies "It is my bike and my indicator. I have the freedom to do whatever I want with it!!! What is your problem?!"
What can I say.
