Not if OEMs don't have the technology. Making cars is the easiest part of self driving. Once you have the tech, you can farm the manufacturing out to many OEMs (like Waymo is doing with Hyundai and Geely) and then OEMs become the middlemen.
Tesla self-driving doesn't exist and will only work on Tesla vehicles if they ever develop the capability.
Waymo self-driving works now and has been demonstrated on multiple vehicles. Waymo could utilize the manufacturing capacity of the entire auto-industry.
