GM wants to use artificial intelligence to sell you stuff while driving

General Motors has partnered with IBM to add the latter's artificial intelligence smarts to its cars. IBM's Watson will be used to augment GM's OnStar service, which currently offers features like vehicle tracking and turn-by-turn navigation for a monthly subscription fee. The upgraded OnStar Go, though, seems to be more about advertising than anything else. GM says the main use will be to let drivers "connect and interact with their favorite brands," with Watson crunching data on users habits to deliver personalized services. Depending on your outlook, some of these services could be genuinely useful.
