What are Tesla owners actually doing with their in-car web browsers? That’s the question that ad measurement and targeting company Quantcast tried to answer with some just-released data.

Apparently, the Tesla Model S (of which there are now more than 25,000 on the road) includes a 17-inch touchscreen with a web browser, and yes, it works when you’re driving.

To see the kind of browsing that someone might actually do in a car, Quantcast used a browser identifier to isolate Tesla visits to 100 million sites over a 30-day period. Focusing on properties that received more than 100 pageviews, the company tracked 463,000 PVs from Teslas over that period, and it says news sites accounted for an unusually large amount (54 percent) of traffic — Drudge Report alone represented 10 percent of all Tesla pageviews, with finance news sites collectively representing 13 percent. In the news category, local sites made up 26 percent of all visits.

Quantcast also found relatively uniform usage between 7 a.m. and 6 p.m., which seemed surprising — in a blog post, the company wondered, “Do Tesla owners simply drive all day?” Well, there were some differences across that time period, with entertainment usage higher during midday and news during commute hours. Quantcast said it’s saving the question of whether those are the same drivers browsing through the day “for a later analysis.”
