I have personally been doing all maintenance on my families 4 vehicles for 20 years. They rarely rarely go into the shop. I personally replaced the heads on my truck and personally replaced the clutch and entire breaking system recently. I do more auto maintenance than 99.9% of folks out there. My truck does not have a power steering motor. It has a $100 power steering pump driven by a belt rotated by the trucks engine.It was said in the Munro video with the head engineers that the dual powerpack motors on the Sbw rack each provide steering input, but each motor alone is capable of providing 50%-60% of the needed power for high steering load applications. So yeah, they're double for fail state redundancy.
The fact that you don't realize that there's a motor controlling your power steering is a testament to their reliability. I can only think of two consumer vehicles on the market that still use hydraulic steering: Toyota Tacoma and Subaru WRX STi. There's a lot your electronic power steering (EPS) does that you might not even realize. Wheel imbalance feel reduction, constant drift mitigation, soft end stops, road noise feel reduction... etc. Since the physical connection between the hand wheel and steering rack is gone in the Cybertruck, many of those features will be more invisible to the end user, but will definitely still exist.
