The Chrysler 300 may be the best modern sleeper car; when equipped with the SRT8 package, and a non-vanity license plate to let people know you have a SRT8. Most likely this owner thinks making the car identify as being self aware is ironic.

However in another dimension this person could be advertising that they are driving a hot as in it may be a stolen SRT-8 or maybe they felt like they got a really good deal on the car (which would never happen on a relatively rare 300 SRT8).
