One could derive a lot of it from GPS or message data alone. But the list sounds a lot like what you might get from a data broker, so I'm presuming that's where its actually coming from.

But to directly answer your question, imagine you're data mining a car's infotainment and come across the following queries... you may be able to infer some things from these entries:

"fertility clinic", "gay bar", "gentleman's club", "synagogue", "bankruptcy lawyer", "mobile home sales", etc.
