Autorickshaw economics

Today, while I was returning from a Shopping mall in bangalore in an Autorickshaw {Autorickshaws are 2 stroke, 3 wheelers which are a common mode of transportation in India. [Equivalant of taxi's in the US]} the autorickshaw driver said something to me in Kannada [local language]. I couldnt understand it, but, out of curiosity, I said "Nannage Kannada swapla swalpa gotthu; Hindi, English, Telugu". {this is what I usually say when someone talks to me in Kannada - I know very little Kannada. These are the languages I know}
The driver (about 25-30 years in age) then told me that he had been waiting for a passenger from 1 o'clock, and he did not get a single passenger till the time I asked him to take me home [It was 3:15. He had been idle for 2.25 hours!]. He also tole me that, he would have gone home if I hadn't boarded his auto.
The driver seemed friendly, hence I asked him some more questions. The information that I got is as follows:
mileage of an auto - 20 km per litre of petrol (gas). This costs him 2.5 Rs per km.
The standard charge is 6 Rs per km, thus he makes a profit of 3.5 Rs per km.
He travels close to 80 km every day [excluding the "idle" rides]. Thus, he earns around 280 Rs [7 USD] per day i.e. 2,600 USD per annum . That is pretty low as compared to and average engineer's salary [12000 USD per annum].
I can help these guys by getting them passengers. Using mobile phones to connect the prospective passengers to the idle auto rickshaws. I'll post the details of my idea soon.
Now, back to android!
