OK, I misunterstood this. However the link provided by @vadim is still not relevant to the issue at hand. The only takeaway from this link is that lists in CarPlay seem to limited to around 1.300 entries (1/3 of 4.000). This should be more than sufficient to list all Albums by an Artist.
When driving alone, I usually ask Siri to play a certain Album or song. This gives mixed results, but that’s another topic and certainly not an ARC issue 
.
When driving with my family, my wife or kids often select music manually from the Infotainment screen. Also when stuck in traffic I don’t see any safety issues with accessing the Infotainment Screen manually. My Car also tends to issue a warning, when it thinks, that the driver ist being distracted from driving.
I agree, however “reduced function” in my eyes isn’t the same as “limited function”. A reduced GUI means that certain functionalities are left out completely, because they are considered being too distracting while driving. It doesn’t mean that functions that have been implemented should be incomplete.
