If the electronic power assist steering controller fails during use, the rack falls back to manual mode where the steering is heavy. I wonder if they were collecting data on how many units fell back to the backup unit, and decided it was enough to either not use it, or pay the warranty costs for fixing them. There's really nothing in the EPAS system that can wear out, maybe the motor itself...
FSD is trash, all these Teslas on the road braking to a stop for no reason, driving slow in the fast lane >:( Cut them off the computer wont care.
