Forget me not

Unfortunately, there have been several disasters lately, caused by children being forgotten in parked vehicles.
However, there is one thing we will never forget in our car -- our cellphone...
The 'Forget me not' application will use your cellphone's bluetooth connection as an indication of the beginning and the ending of a drive in the car.
When you start driving, the application will inquire whether there is a child in the vehicle.
If a positive response (or no response at all) is given, when the drive ends the application will ask whether you have removed the child from your vehicle.
If you do not confirm that the child has indeed been removed, the application will make sure to remind you...
