"For a scientific study it's really lacking facts which makes this is little more than fluff journalism/science." Did you actually read the study, or just the piece on ars? There's a link at the bottom of the article to the actual study, but I don't have a PNAS login so I can't confirm/deny your assertion. If you're basing your criticism entirely off of the ars piece, though, I would tell you to pump your brakes a bit. They summarized the study, which is typical for this sort of journalism, and in my opinion worthwhile -- as long as the summary matches the actual findings of the study. "For example I have an Infiniti(G35), a Lexus(IS250) and a Nissan Economy Box (Versa)" I'd probably be able to take your response a little more seriously if you didn't immediately establish that you likely have a higher SES (owning three cars, two of which are "luxury" brands), and then fired off what seems to be a series of kind of defensive attacks on the study.
