maybe a bit weird subject as we are talking about bikes most of the time, but we just bought an old van so we can transport many bikes and sounsystem on tricycle and stuff from and to our voluntary bike coop, Bikekitchen Bratislava in Slovakia. We are now lookiing for some policy for sharing the car in our community, even though we trust each other we would like to have some rules so everything will work fine. We expect three kinds of use - mostly use for purposes of our bikekitchen, then renting it to friendly coops and then personal use of our core members.
