Researchers connected each vehicle to a custom WiFi access point and logged all outgoing traffic.

The article talks about both apps and the vehicles themselves. I would really like to see more info on what the cars do when you take the apps out of the equation. Are there any that don't phone home unless you explicitly give them internet access?

A study about the results will be published this week.

I look forward to reading this.

Edit: actually there's quite a bit more detailed info at https://automatictransmission.khoury.northeastern.edu/
