Of course, saying this the first thing I think of is Cars.com commercials - they use this as their brand name and they show up for it - perhaps big enough for a manual approval - who knows - all speculation of course.
Because Cars.com calls themselves "Cars.com." They don't go around calling themselves "Cars" and expecting people to know what that means. It's an EMD that has been branded and have built authority.
