Child Unattended

If the back seat belts are engaged the vehicle will not be able to be turned off and a chime or verbal prompt will 'remind" the driver to "check the back seat". If after a few minutes the seat belts have not been disengaged the windows will roll down and a loud "child unattended" alarm will sound. If winte,r perhaps the windows stay up and the vehicle mantains a 72 degree inside temperature with windows up but car unlocked.

i don't know how feasible that would be. for example, if you stop to get gas everyone else may wait in the car with their seatbelts on. and having anything unattended unroll windows could be bad (rain, thieves, etc.)
