I've recently grown fond of using the car to watch movies. It's pretty relaxing in there when you're just parked somewhere.
I use my trusty PSP and just hookup the audio to the aux of the car. Of course i turn off the engine cause i don't want to waste fuel while watching a movie I just leave the key there so i can still use the speakers..
I've been wondering if there are any problems with doing this like 2x a week..
(I'm concerned about the battery discharging etc.. )
