I don't know why I didn't think of this before

If I were a smart manufacturer of cars, I would install huge, beautiful, expensive OLED LCD screens in the cars I build. I would then offer the cars to consumers at a high price...

...or I would offer it to them at a much lower price, and in exchange I would require that they open access of their ultra-lavish screen to vendors.
In the meantime, I would sell rights to vendors to broadcast commercials on the screens at a reasonable rate, for a reasonable fee.

Watching "Monsters, Inc"? You must have kids in the car, and the GPS verifies you are nearing a McDonald's! The movie pauses, and your kids watch a commercial showing the awesome toy they could be playing with in mere minutes if only they convince their parents to stop at the aforementioned Mickey D's.
Watching "The Hangover"? You might be interested in knowing that the following nearby bars have the following drink specials.
Is it dinner time? The following restaurants are right in your path, and here are some delicious items on their menus.

Essentially you are doing exactly what Google's Ad programs do. They cater to their viewers best by identifying trends in the user's searches and location. The same could work here. If a user's screen shows macho action movies mostly, or the user fits in the single male 18-49 demographic, or a host of other indicators, the gorgeous LED LCD screen could target that driver/passengers with ads that he/she would find appealing. Location would also be key. McDonald's could key up a quick ad when your car was approaching a nearby location. In the morning Starbucks could point out how fantastic their chai lattes are and then suggest you turn left, a Starbucks is "only a block away..."
The possibilities are virtually endless. And as the smart car manufacturer, I could charge those businesses top dollar for access to my drivers. It would quickly offset the cost of that large screen I installed in the car, and then continue to be a source of revenue as long as the car was on the road.

Of course, we wouldn't want the insanely awesome screen to distract the driver. More on that to come.
