Car Power Inverters: Still Not Built In?
Your big 3/4 ton pick up might have an AC power plug built into it somewhere, but where is the one in my Lanos? (it’s a Daewoo….) The Civic? Camry?
iPods and MP3 Players sent a huge demand through the auto industry for built in 3.5mm inputs. Those devices need power though dag-nab-it.
I think it should be easy to prove that with the huge increase in sales for power inverters, the demand is there.
Even if you don’t own an AC power adapter/inverter yet, if you had a plug built into your car you would use it for sure. For a laptop, charging station for phones and iPods, you could take your toaster with you too. (pop tart heated in 3 seconds… ding-bang! Food on the go, even faster. Eat that Brian Regan.)
Bueller? BUELLER? Come on auto-indsutry . . . . we need this, stop slacking off. I don’t need 5 new $3,000,000 concept cars each year that will never get built. I need more functionality from the cars that do get built. I need to get all this crap in my front-wheel drive 700 lb. car, and I want you to help me.

List: Car Companies Who Are Slacking Off
As much as I think you are right on the practicality level, you have forgotten how unsafe most of the items you listed are in a car. The one old lady at McDonalds who spilled hot coffee on her could turn into a nation of people who burned themselves in their car. Sure, laptops and iPods are same but it is the redneck abuse that gets car companies in trouble. If they do put an inverter in a car, what is a safe wattage to allow in the car. If they burn themselves now on a store bought inverter, the car companies have no liability - the inverter company does. Once it is baked into the car (pardon the pun) the company becomes liable for stupidity and we all know there isn’t enough of it out there these days.
