When we were going to Marottichal last Sunday, my friend Amal Raj was using a GPS tracking app on his mobile phone. Though it was not necessary for us because we know most of the way, we still pondered over it just for the fun. It showed us the speed we were going, how far to our destination and how much time its needed to get there.
It reminded me of one time when one of my friends who was working in the transportation business told me about the importance of GPS based fleet tracking for their business.
