We generally revile taxi drivers as a profession. They drive too fast, they drive too slow, they cut other drivers off abruptly and slam on their brakes at the last second to pick up a fare.
Must be a cut-throat business with so many cab drivers plying the streets competing for a dwindling number of potential passengers. With so many strange fare surcharges these days, people are starting to consider owning their own vehicles as a cheaper option for getting around town.
But look! In order to obtain a bigger slice of pie per cab driver, instead of competing each other off the roads, they're building a communication network to share information with each other.
Expanding market share by killing competition: Bad. Expanding market opportunities by sharing information: Good. Cooperation is the name of the game, people! Sesame Street may have had it right all along.
