Basics

A system of Car Rental / Community Ownership, where rather than each person having a car, they use it when needed
Can be especially relevant for non-routine use (ie the area is Walkable / public transit is available for some things, but a car may be needed for longer trips), or for specialty vehicles ( (mini-)vans for people, or cargo vans or pickup trucks/flatbeds for cargo)
Thus each person essentially has a fleet of cars for them to use!
There are many services, but two main "categories/types" of sorts
- Fixed Location(s)
- Peer to Peer (Just park it, and leave it for the next person to pick up)
They are also usually managed/interacted with online via a website and/or app

Existing Services

Type: Peer to Peer
Monthly Fee (No for driver, and no for vehicle owner)
Price: Free to sign up as a driver and free to post your vehicle to rent. If rental owners opt for Turo Go, the hardware installation costs $190 and currently doesn’t have a subscription fee.
Rental rates: Daily rental rates start at about $20 for older and smaller vehicles but can easily top $100 for premium models.
How much rental owners keep: Rental owners keep 65%, 75%, or 85% of the rental rate depending on the vehicle protection plan picked.
Mileage limitation: Since it is set by the owner, mileage limitations can range from as little as 100 miles a day to unlimited miles. The normal amount is 200 miles per day, and if you want more you have the option to pay additional for it.
Gas: Not included. Drivers pay for their gas and must return the rental with the same amount.
Rental length: Turo only offers daily rentals; minute and hourly rates are not available.

Type: Fixed Locations
Monthly Fee (No for driver, and yes for vehicle owner (+ requires unlock hardware) )
May just be rental, need to find more info on car owner side

Type: Peer to Peer
Monthly Fee (Yes for driver, and no for vehicle owner (+ requires unlock hardware) )

FLOSS (need to look into hosting and how all that would work)
Peer-to-Peer and Fixed Location(s) Supported
No Monthly Fee (Maybe transaction fee, again largely dependent on hosting)
Both on demand usage, and reservation based systems supported
Support for:
- Face to Face Key Exchange
- Key Lockbox Based Key Exchange
- Some sort of wireless unlock (need to try and plot security wise (rfid/bluetooth/wifi etc may be *very* venerable to hacking/password theft etc?)
App (For Android, and iOS (ios is odd with their app store so that may be less possible) and Website
Allow car owners to have a profile/management system where they can decide how they want to do it + enter all info, and thus create all the tags for the prospective users to filter through
Maybe add some sort of long term maintenance cost / driven distance added pricing to take care of that issue?
Probably require fuel up and/or maybe just reimbursement (so you don't constantly fill up when at 85% capacity etc)
Hourly and Daily Rates (+ car owner designations for what is allowable)
No in-car smoking allowed, probably make some sort of "code of conduct" with penalty/ban and/or just cleanup fee to discourage/prevent people from leaving it a mess
