The reason I mention AI is because the article talks about AI tools to predict accidents as well. I also googled Openpilot and this is from their wiki page.

In contrast to traditional autonomous driving solutions where the perception, prediction, and planning units are separate "modules", openpilot adopts a system-level end-to-end design to predict the car's trajectory directly from the camera images. openpilot's end-to-end design is a neural network that is trained by comma.ai using real-world driving data uploaded by openpilot users.[34]

So uh. It might be AI

Also it seems openpilot requires hardware for the cameras and stuff, they aren't going to strap third party cameras to cars to sell new. They'd have to implement the sensors in the car itself, and doing so would cost more than nothing.
