PROBLEM
People tend to forget to roll up their windows, especially the back windows after exiting a vehicle.
Vehicle users have to manually press a button to roll up windows before exiting the vehicle.
Cars do not automatically roll up all windows when a vehicle is turned off.
Your vehicle should sense based on weight when all people and pets have exited the vehicle and automatically roll up all the windows.
PROPOSED SOLUTION
ALGORITHM PSEUDOCODE
func rollUpWindows()
If vehicle is off:
For each seat in the car get the seat weight sensor data
If all cu
ent seat weights are greater than the standard seat weight:
Leave windows as is
Else:
Roll up all windows
Else:
Do nothing

Child Safety
Although children should never be left alone unattended, in the case that it does happen, it is guaranteed that the windows will remain rolled down for air circulation.
Pet Safety
Stolen Items
Similarly, to child safety, if pets are left alone in the vehicle it is guaranteed that the windows remain rolled down for air circulation.
Windows will never be rolled down if no one is inside the vehicle, therefore, a thrive must
eak the window publicly to steal items from the car.
COST ANALYSIS
ITEM COST
Car software update * ~$100 per ca
Weight sensor* ~$330 per seat
* Weight sensor cost calculated based on the average replacement cost of an ai
ag sensor from two sources.
* Given that this is a proposal for a new car, it is assumed that the car has modern day software capabilities.
