How future cars could share Internet access – all over town

Within a few years, auto industry experts predict most new cars on the road will be Wi-Fi enabled. A new algorithm developed by graduate students may let them share expensive links to the Internet.

The idea is that Wi-Fi is cheap, but surfing the Web over a cell or satellite network is expensive. If we could pool our data needs via Wi-Fi and use a handful of 3G connections instead of hundreds, we’d save money and bandwidth.
