但是dash cam的音频怎么算？

您给的链接上说：

Dash cameras obviously can make a visual record of the road ahead, but under state law, they must also be capable of recording and saving audio data. Because this requirement raises privacy concerns, you must post a notice in a visible place in your car that notifies passengers that their conversations are being recorded. The owner or lessee of the vehicle can turn the device off at any time. The information stored on the recorder belongs to the owner as a matter of law.

如果我开着dash cam，也标记了提示，发生车祸后，和对方的对话之前，我还得提醒她我的dash cam可以录音？

如果我开车时有蓝牙电话打进来，我也得告诉对方我在录音？

这也太麻烦了！
