At the most recent Consumer Electronics Show in Las Vegas, it was clear that automobile manufacturers have gone from touting the look and feel of their cars to highlighting their technological bells and whistles.

Cars now automatically update their software without going to a mechanic, and drivers can download features that let them shop, order food and read the news from their dashboard. But questions are emerging about what’s being done with the vast amounts of data these cars can collect, whether it’s a driver’s song choices, their weight or how fast they drive.

“As there is now a technology war developing in terms of new car models, with each one trying to offer more connected features, it does beg the question whether the implications of all that data collection and use have been properly thought through,” said Pillsbury partner Rafi Azim-Khan, who leads the firm’s Data Privacy & Cybersecurity practice in Europe.

Another concern is that while automotive companies generally remove the capability to watch TV while the car is being driven, that feature can be open to abuse, Azim-Khan warned.

“I can’t imagine that it would be impossible for a very determined person to put up on the web some kind of hack or cheat where you could turn that feature off,” he says. “Something like that would bring in a whole host of additional regulatory concern.”
