Skewed data is skewed

The team compiled a top-10 list, which classifies the percentage of drivers with a particular model who have past speeding tickets versus those who don’t, not the percentage of speeding tickets compared to drivers as a whole.

More than 20 percent of WRX buyers included in the study had past speeding tickets, for example, giving it the top spot on the list. About 11.3 percent of U.S. drivers have a past speeding ticket, the study said, making the WRX about twice the average.

OK so they are not comparing apples to apples.

The study was done by a U.S.-based insurance-comparison company Insurify, which said it sifted through its database of more than 1.6 million applications for car insurance. Since drivers have to put in personal and vehicle information to apply for quotes, including the model of the car and past speeding woes, the research team had plenty of numbers to compare

All of the cars on the list were pretty normal ones, probably because the folks with the louder, faster, more expensive cars either know better than to call attention to themselves on public roads or they don’t care to waste their time shopping around for the lowest insurance rates on some comparison website

The source of the data sets the bias right from the get go.

Dodge Dart: 14.86 percent
(Shout out to the Dodge Dart for always remainingnewsworthy, somehow.)

This is hilarious!
