It&#x27;s incredibly complicated, but pretty secure. The CAN bus is isolated from the network. I have root access on the CID and the IC (both separate tegra systems). You can even reboot the CID while you&#x27;re driving and you only lose media and air conditioning and such. Accessing the CAN bus requires going through a pretty secure gateway system, so you can only basically make requests. Even then, I haven&#x27;t even really looked into that area much.
