Wi-Fi is essentially free, while cellular data is expensive. The seeming liberation of an always-connected vehicle could easily be constrained by the shackles of an enormous cellular bill. Is there a way we can maximize the “free” connectivity of Wi-Fi while minimizing the costs of mobile data?…

But MIT graduate student Alex Cornejo said math can be used to used to wrestle just such a network out of freeway chaos. He and his colleagues have developed an algorithm that would allow hundreds of different cars to aggregate their internet-bound data and send it compressed over a single cellular connection, thus reducing bandwidth costs for all the vehicles participating.
