If you don't think Google will be doing the same thing with LTE-enabled cars, think again. Their partnership with automakers is no small challenge, and the data gathering opportunity is massive.
Google can know that most Honda Civic drivers in Chicago (for example) park next to McDonald's, and that their phones traveled inside the restaurant -- Facebook will know only that people checked into the restaurant. It stands to reason that Honda could use this information and market the Civic as "the best" car for eating at McDonald's. Maybe Honda Civic drivers get a special McDonald's discount?
Facebook pretty much beat Foursquare to the punch on this one, but (most interestingly) Foursquare relies on OpenStreetMaps -- what does Facebook use? Is it proprietary? What is "Places Nearby"?
