What makes a good rideshare service?

We have been thinking and developing in the rideshare space for almost two years now and we think we have learnt some things.

So - what features does a compelling, successful rideshare website need to succeed? This is an important question, especially as we try and bring Cooreea to the worlds attention.

1. Easy navigation and ... maps!
   
   
2. A healthy trust system which promotes mutually beneficial interactions between users. The worst thing in the world is to be packed up and sitting at a cafe waiting for somebody who does not show (it happened to Stefan :-)
   
   
3. Some way of proving a contract has been completed, essential for the trust process and useful for exchange of money associated with giving a lift.
   
   
4. Other users! It ain't no good listing your journey if there is no on to match to

This might all seem a bit obvious, but it serves as a guide to us. We for instance do not see Gumtree rideshare listings being viable in the long run while their system does not have an adequate ID and trust system.

It also shows us what we have to do next, we have the features, we need to find users !!
