From the article (I added emphasis):

"The observers tracked the make, age, and conditions of cars, using them as a proxy for class. High-status vehicles such as Mercedes were considered the provenance of the rich, and those driving them were about three times more likely to cut in than those in less flashy cars."

While it makes for flashy and shocking headlines (the business of the news today, no?) this study is practically worthless. So they ASSumed that make/age and condition of cars is a proxy for class...so every person who drives a late model Mercedes is wealthy? I guess the people conducting the study haven't heard of low mileage leases and buying on credit.
