`  :Personal car sharing and peer to peer car sharing pertain to individually owned cars. Thus, the distinction here is based more on the ownership of the vehicle rather than the ``time of rental``.  This is a niche under the topic car sharing. Car sharing encompasses all forms of car sharing (B2B and P2P car sharing). The public needs to be able to distinguish between B2B and P2P car sharing as it is a distinction that people understand and for which they are searching for in search engines. Therefore, whatever title distinguishes between B2B and P2P car sharing would be appropriate (e.g. personal car sharing or peer to peer car sharing, or neighbor to neighbor car sharing, or friend to friend car sharing, etc).`
