I've left my phone in my car for the umpteenth time now.
I think the car should have a way to alert the owner if they're walking away leaving the phone-key inside the vehicle.
IF phone key inside the vehicle
AND seat sensors recently turned off
AND vehicle door recently closed
AND ultrasonic sensors detect a person walking away
THEN make an audible alarm and flash the lights
Now, the only question I have is can the car distinguish between a phone inside the car and outside the car? Does Bluetooth connection record strength of signal? Or is it binary as connected/Not-connected?
