Awesome! I never actually thought of that.. I think the next step is to focus more on the analytics part and extracting interesting insight. That's where the actual value is imho.
Is this information you can't get via their API?
So far, yes. Their API is geared towards allowing developers to provide services on top their offering (On-Demand delivery and whatnot). I have a hunch that they will never release analytics for their riders. It's not a priority and it doesn't drive more business.
