Or it could be a feature in the Lyft app that they said it was not the case but who believes them...

If it's in app, there would be an obvious microphone consent pop up and usage indicator.

If the conversation was recorded with the microphone on the driver's phone, and the Lyft has different apps for drivers and passengers, mightn't the microphone consent only appear to the driver, and not to the passenger?
