Using GPS to catch tampered rickshaw meters (Updated)

tejvan - 20-MAY-2010

I always carry my trusty GPS whenever I head to places I haven't been to. It helps me to quickly locate a place and I don't have to ask for directions. I dont have a vehicle and so I invariably take rickshaws for trips within the city. The infuriating thing about rickshaws is that their meters are frequently tampered with. Yes, even the digital ones.

Yesterday I was heading out to Vasant Nagar in an autorickshaw and carried my GPS with me. The GPS has an odometer which measures distance covered to a very high accuracy. The rickshaw had a "PERFECT" digital meter (model A-786). I quickly realized that it had been tampered since it indicated 2 kms when the actual distance covered was only 1.5 km. I watched as the gap between the GPS reading and the rickshaw meter reading gradually widened. Towards the end of the trip, the rickshaw meter was off by more than 2 kms and still growing.
