That means lowering overall costs, especially during times and routes that would be unpopular for drivers and thus cause surge-pricing. In other words, instead of paying surge-pricing for a driver, you could just drive yourself and/or pick up other passengers on the way to supplement your ride-share cost.
It would basically combine car-sharing with ride-sharing within a single, integrated platform.
