Chevrolet has become the first carmaker to offer an unlimited data plan with its cars. From a report on BBC: The deal, for a 4G LTE data plan, applies to cars sold in the US from 3 March and will cost $20 a month. It is being offered with the help of US carrier OnStar and will see vehicles fitted with a wi-fi hotspot that connects to the web via LTE. Chevrolet said it was offering the deal because in-car data use had grown so fast. Figures gathered by Chevrolet suggest the amount of data used via wi-fi in its cars jumped by 200% last year. In 2016, it said, Chevrolet in-car hotspots had handled about four million gigabytes of data. The LTE-based hotspots are available across the entire range of vehicles made by Chevrolet.
