I appreciate it might not seem intuitive but there are circumstances where this is very useful for both the customer and the owners. For example, in the event of a breakdown where a booking is transferred to another van.
We used to allow owners access to the full contact list of all other owners in the community but this was misunderstood (and therefore misused), so now it is restricted to only owners with customers in common.
In addition to this, we have the google group which you can reply-all to (albeit on approval only) and the Owners Facebook group.
Our feeling is that owners should have easy access to contact other owners because there is a lot of shared knowledge and being able to interact is of benefit to all parties involved.
If at any time you have access to something you think you should not please do, please send screenshots and let us know.
Thanks again for raising this, questions, suggestions and feedback are always welcome!

The behaviour you have noticed is actually intentional. I know this may seem counterintuitive, but the system is designed such that once a customer is linked to your location, you will have access to their full history. This is necessary and useful when we have repeat customers, or in particular if we are transferring a customer's booking from one vehicle to another (especially at short notice).
As the owner, you are a data controller and are bound to keep safe the personal information of all customers that are linked to your location (even if they end up not completing the booking, cancelling, transfering etc).
We understand that there are situations, as you have described, where it may not be necessary to share the full details with the new owner yet, or with the old owner; however, the timing of that need is hard to define. So we decided that the improved usability for both owner and customer outweighed any potential risk of the exposure to an additional data controller, given that they are both bound by the same contractual obligations.
