Startup Idea : Points to ride

Idea is based on carpool concept. Online app that will connect riders to drivers. Based on time of day, distance, traffic, driver rating etc. app generates points that will be credited to driver and the rider will have to purchase those points if he goes out of it. Once driver gets the points he can in turn use it for himself as a rider and pass to onto other driver so and so forth. This will create a ride sharing economy and save cars on the roads, traffic, gas etc.
