Chevrolet today became the latest automaker in the US to add roving Internet access to its vehicles. The Avalanche, Equinox, Express, Silverado, Suburban, Tahoe and Traverse all now have an after-sale option of an Autonet router that provides a 1.5Mbps connection even at speed. Like the Chrysler option, it accomplishes the feat by sharing a 3G link over a local Wi-Fi hotspot that shares the connection with passengers and those within a 150-foot radius.
