Sometimes it takes lots of research to figure out what we knew already. Wired's Autopia reports on a survey of vehicles at the recent Frankfurt motor show by the Telematics Research Group, indicating that only 21 of 225 vehicles offered an interface for the iPod (standard or optional). That carmakers are leaving to the aftermarket a business they could keep for themselves is only the glass-half-empty view. That those long-production-cycle guys have included it at all within five years is astonishing.
