One potential downside could be the danger of drivers trying to manipulate their mobile devices' cameras while in motion. The concept could be more passive, for example, by using a road-side camera to identify drivers by license plate. The rewards would then be given to drivers who had registered in the rewards program beforehand.
In addition to time-based paradigms, the deal could also be location-based to motivate people to choose alternative routes.
The same concept could also be used to influence the way people arrive or exit from events or concerts - again to reduce traffic and congestion.
