These young ones are getting their cue from the older ones who are also quite fond of unrelenting idling and tearing all over creation. It is quite normal here for people to drive two blocks for something rather than walk it.
It is evident to me that even though people complain about fuel costs, they must on some level realize that fuel is a minor component of overall vehicle cost, and they are treating it as such. One example would be the Auto-Start, seemingly the greatest invention since sliced bread. What we have here is a sea of idling vehicles with nobody in them. It is this flagrant waste and extravagant consumption that leads me to question the desire to drill baby drill the U.S. at this juncture.
