Temporary Bluetooth Pairing

Windows, Linux. iOS, Android are collectively referred to by Bluetooth as platforms (platforms enable other applications). And up to a certain extend a platform defines what an application can or cannot do. For example iOS is very restrictive and allows only a very limited set of Bluetooth functionalities. You can do more with Android, but still certain common behavior (like pairing) is defined by the platform.

So speaking of pairing, there has always been an assumption it is for using private devices, forever. There is no concept of a rental car and no concept of a shared conference speaker. If you pair with a car, the pairing is persistent (keys are stored on both ends) long after you return the car at an airport. Many cars even retain contacts databases they download from drivers' phones. Conference hands-free speakers behave the same way. Which leads to many unexpected behaviors, like them taking over a conversation long after you finished using them, just because you happen to be in the radio range.

So may I suggest a simple improvement here? Could I, when pairing a bluetooth device such as a car or a speaker, select if this is a permanent (long standing) relationship or something much shorter - a week, a day or even an hour? And that after that time the device is automatically "forgotten"?

Platforms have so many opportunities to make technologies like Bluetooth better for users. Sometimes they just don't care...
