Hi R_Lewis,

Croeso i OSM - I do understand your frustration about people accessing (your?) land without permission. You did the right thing by adding the access=private tag, however it's still important that they are seen as driveways!

It takes time for data consumers (like satnavs) to receive OSM data, it's not instant.

Please see the Wiki for more information
