That’s Just the Way We Roll
Gizmodo has a few entries called “Justify Your Gadget,” which are usually aimed at “which technology is best?” rather than “what’s the point?” But they get it right about LCD screens (often multiple screens) installed in cars in the unlikeliest of locations.

The trunk? The trunk lid!? The wheelwell? The front bumper? The side window facing out!? It boggles the mind to think that some joker will want one of these installations, but the cynic in me knows it’s coming. ‘Cause that’s just the way we roll, ya know. People gotta know what the driver is watching, see.
These custom installations (mods, if you’re hip) for display at industry conventions probably aren’t intended to be on the street but are merely to show what’s possible. But some fool is going to want this pointless bling. The whole trend toward making cars into rolling living rooms, with all the entertainment options crammed into a limited though mobile space, is just wrong. I think the push toward tiny, cheap commuter cars is more reasonable, though it remains to be seen whether they will be a disposable as some fear.
