Does anyone know if the Reminders App functionality to reming when "getting in and out of the car" can be resembled via API? Is that CoreBluetooth or something else?

I found the trick!

It's neither CoreBluetooth nor CarPlay. It's in AVAudioSession! The AVAudioSession has a routeChangedNotification. So as long as you hold a AVAudioSession you can register for this event:

let nc = NotificationCenter.default
        nc.addObserver(self, selector: #selector(handleRouteChanged), name: AVAudioSession.routeChangeNotification, object: nil)
@objc func handleRouteChanged(notification: Notification) {
        os_log("Route changed.", log: OSLog.App, type: .info)
        session.currentRoute.outputs.forEach { output in
            os_log("Output: %@", log: OSLog.App, type: .info, String(describing: output))
            os_log("Port: %@", log: OSLog.App, type: .info, String(describing: output.portName))
            os_log("Port Type: %@", log: OSLog.App, type: .info, String(describing: output.portType))
        }
    }

This sounds weird to be honest. Are you sure this will work as expected? This should be notification for when user changes any audio output.

Yes sure! That's kind of a misuse. But it's a trick that you can certanly use. You could start location tracking and motion processing to check if you're really tacking a trip with your car. Holding an AVAudioSession is much cheaper on energy that the other two. So it's just a trick to know when to spend more energy.
