2010 - wtf

Ok, who here thinks that maybe, just maybe, we, as a people, by the year 2010 would be able to construct a car - or every car - such that if you by mistake leave an interior light on it would, after a couple of days - maybe when the battery is about to run out of juice - by itself, decide that - hmm, this is probably not right - I will turn that light off so that the owner of me will be able to start me next time he/she requires my assistance?
