If it’s about expediting emergency calls then say so and limit the recording (declared and actual) to that situation. This ‘including, but not limited to’ wording that everyone uses is bs.
The point is that it's not so easy to narrowly construct a legal contract that covers the manufacturers from liability.
Don't you think Mozilla's message would be much stronger if their privacy guide had an example of what the legal agreement should look like? I didn't see anything like this, maybe I missed it. Clearly manufacturers have gone overboard in some cases, but I don't believe it's that easy to make you guys happy.
There are lawyers in the audience here, how about post some legal contract that protects manufacturers from a passenger pressing the OnStar button while the driver is in the gas station bathroom and being liable for anything resulting from that, and every other possible liability from OnStar. I'll take my -4 and your lack of constructive counterargument as the answer I know it is.
