Description

It is heavily rate limited, so if the user engages after a turn where it's wound up, even if Driver+ isn't enabled, the EPS may temp fault because of that (`EPAS_High_Angle_Cmd_Err`):

Research direction

The issue names no file, test, or entry point. Start by locating the Rivian EPS configuration and the EPAS_High_Angle_Cmd_Err signal, then trace how the stock Driver+ angle command interacts with torque. Done should include a reproducible diagnosis and a verified correction, but the issue does not define a specific test or acceptance criterion.
