1. Getting rid of features like passenger lumbar and justifying it by saying few people used it. I've also been around long enough to remember they temporarily got rid of side-dimming mirrors on Model 3, only to bring it back months later. Supply chain woes or whatever - it's better to be transparent about this.

2. Getting rid of features like ultrasonics and not having a production-ready hardware or software solution for things like Park Assist. When the move to vision-only Autopilot was made, there were also several limitations to the vision-stack.
