Dashcams are fully prohibited within the EU, in Austria, Portugal and in Luxembourg. In Germany (big market) are allowed only if the files stored are regularly deleted maintaining only the last few minutes. Other EU countries have also specificities but are in general tolerated.
This functionality, having the possibility in setting the innovv cams (I have a K2 but not using it anymore because of this issue) in deleting stored files after a fixed period of time (5 minutes, 15 minutes, 1h, etc...) would make them more compliant and aligned with EU GDPR regulations, what would be relevant for some people as it is my case.
I presume that this would be just a not difficult software "evolution".
