Ok. What I'm saying is that the ability to accept and relinquish an automated security deposit does not require a decentralized technology such as ethereum or even bitcoin.
A machine (like the one I linked above) can accept money and dispense money at the discretion of the business rules that determine the appropriate criteria for these operations (via car sensors or whatever).
> Yes, but that requires a fixed machine (or a cash lock box on every vehicle?).
Of course not. Do it exactly like how rentals work today except in an app instead of in person. Put in your bank card info, a hold is placed on your card, when the vehicle is returned the hold is released and the service fee is charged.
