I've been using multiple mirrors for years. Haven't thought about someone "new" to the experience, but I would imagine it does take some "mind" adjusting. On my new truck, the top mirrors are set for normal road driving, to watch for passing cars on both sides, like any normal mirror is used. The bottom mirrors are set out pretty far so I can clearly see the trailer tires and how they track, especially the passenger side. The second mirror is angled pretty far out-there, and only when turning corners do I use it. Then the top one is completely ignored.
