Every Bones episode:
[Characters are in the car.]
Booth: "Whats that beep, bones?"
Bones: Its adaptive cruise control. The Prius blah blah blah detects blah blah blah. [Shoot to footage of Prius gauge cluster.] Its pretty neat.
Booth: So its smarter than our victim.
Its not even subtle. The FBI guy used to have a Suburban and Bones used to have a Mercedes SL. The two people working in the lab now have a Sienna.
Its nauseating, and not just because they're bland balloons, but because of how blatant it is. I'm completely removed from the story.
I prefer the way GM placed the Cadillac CTS in "Burn Notice". It got a mention "Oh yeah thats my new car" and made several appearances. Nothing obnoxious.
