Imagine a car that learns about its driver and his or her style, has up-to-date traffic information and works out the most economical navigation route. A car that provides entertainment and information, lays on a concierge service, helps out in critical motoring situations and links up with smart phones. BMW has just such a system in its future, called Connected Drive, and it has a whole raft of other cool features as well. The technology is already here, now it's just a question of implementing it.
