My complaint (from above, not the only problem with cameras) about the rear camera is that the cheapest way for them to be installed nowadays, given that other people want infotainment systems, is for them to go hand-in-hand with an infotainment system. Whether the camera is on or not, the car is now vulnerable. The sin being committed is having too much code, especially too much untrusted, untested code (it's "just a radio") wired into the canbus. Toss in a little auto-update functionality and some always-on antennas, and you have all the makings of a nasty exploit. Last I checked, none of those have been known to be exploited in the wild, but they've also not been patched in the last decade. It's a fundamental design flaw that saves a few dollars, so it persists.
