Auto rickshaws are motorized three-wheelers. They are common all over India and provide efficient door-to-door transportation. Auto's can also be shared. My record: 10 adults and 1 child!
Travelling by auto shouldn’t cost you more than Rs5/km (+50% at night). Fares are set either by bargaining or by using the meter (the fare is directly linked to the number of kilometres). You might not have the choice. From past experience, I often had to bargain in Delhi while the meter was almost always used in Bangalore.
Avoid being fooled:
-When using the meter, some drivers take the longest possible route to increase the fare.
-Most meters are tampered or defective.
-If you feel you have been fooled, don’t pay directly. Take the auto-number and make sure the driver sees you taking note of it. He will undoubtedly ask you what you are doing. Tell him you plan to call his boss. He might spontaneously reduce his price. It worked for me.
