Status hasn't changed since the initial announcement 2 years ago...
They are mainly exempt because most of that data is emissions related. ODB came about due to CA requiring lower emissions and smog checks. They needed a way to quickly and cheaply verify it independently of the manufacturer. Unfortunately, in VWs case, the law assumed the data isn't modified before being sent.
We need OBD regulations to be updated for reflect these new technologies. I think hydrogen vehicles are also exempt.
Right now, I'm doing about half of that but I am rcloning data between 2 ceph clusters. (Proxmox and a arm rook ceph cluster).
I'm trying to do similar.
They will continue to get eaten by manufacturers that can control the entire stack, from servo firmware all the way up to infotainment.
