Sent with Siri Privacy Violation

The info sent to a recipient that a message is “Sent with Siri” should be able to be toggled on and off. By sending this information, this can tell somebody that a person is traveling and is using CarPlay to send a message. Granted they may simply be using Siri to type the message, but it is still a privacy violation. Apple should make this an option that can be toggled on and off by the user, or simply delete the “Sent with Siri” message altogether as it is not necessary.
