You probably already have them - they have been on Euro spec cars for ages. I think they may even be a legal requirement, if not, certainly very common. My 2015 spec eurobox has them - nothing special - just hazards flashing under very heavy braking and staying on after emergency stop. I don't think they are allowed in USA and less common outside Europe which is probably why its notable update.
I tested the feature after the update. I drove to 32mph and stomped on the breaks until the car stopped. But no hazard lights came on. So I guess I don’t have it??
