A member of the Bellman Nation just bought a late-model Ford Focus. A cute car in good repair, fairly described as a modestly priced receptacle. Nonetheless, there were two features that I hadn't experienced. One dashboard button activated cabin lights in the footwells and drink holders. The cool part is that the lights are in half a dozen colors, cycling to a new color each time the button is pressed. It's like a rave for your ankles.
The other feature of note is the car's bluetooth integration. After syncing a cell phone, a small text display on top of the dashboard will list caller ID information on inbound calls. It will also use a text-to-speech function to read incoming text messages through the stereo speakers. In that mode the radio tuning knob can be used to cycle through a list of canned responses.
It turns out the engineers did not include a reply for having the car robotically repeat "wax balls".
