@markd Didn't come up in discussion (apologies, nature of doing radio and being interviewed) but appears to be implemented with some obfuscation built in: "There are 3 levels of info that you can share with your digital driver licence:
Full licence: This view shows info about your right to drive. You can share this view when you need to show police things like licence status, classes, or restrictions.
Identity: This shows your basic ID info — name, address, and signature.
Proof of age: This view shows that you’re over 18. It won’t show your exact age or date of birth."
