The APS? is a system that would take your vehicle and park it into bays that would hold the vehicle. This essentially places the platform the automobile is on above another automobile. This non touching stacking is done to assure there is maximum storage available. It also stands to reason why the APS will take 4 floors of the building. There will be enough spaces for 150% of the number of households in the building.
This will mean the elevator will go from 1 to 6 skipping 2-5 along the way. If a technician needs to come in, they will have the resources they will need to do any repairs. There will be ventilation systems in case there is carbon monoxide detected by the system. This will force the CO out of the building through these vents in the garage space. These vents are grated so no creature beyond bug size can get it. For the APS to be use, the user must have an active credit/debit card. This card will be used for paying by the hour. Those with leases will not be charged again, and there will be no charge made to the card, even if that charge would have not been collected.
