However smart your car might be, there's only so much it can tell you by itself. Wouldn't it be nice if cars regularly shared helpful driving info beyond what you offer in mobile apps? Here thinks so. It's launching services that will have cars automatically sharing real-time data to improve commutes for everyone. Vehicles (starting with those from Here owners Audi, BMW and Mercedes-Benz) will use their sensors and cameras to offer details on free parking spaces, traffic conditions, and road hazards. You'd know that a parking spot has opened up, or that heavy rain is forcing drivers ahead to slow down.
