The older Cessna had a lot of information available but was only semi-integrated. You needed a good "scan" to keep up with things, but, when a screen went dark you had other places to look and other sources of information to work with. Not a bad thing.
The newer Cessna goes a lot further down the road of total information integration. And that can be a fine thing (I remember flying behind my first HSI and thinking, "wow, this is easy!). But if one of those Cosmic Screens goes dark, or wonky, you're in a dicier situation. Pilots used to looking in only a few places for data tend to not do well when coping with system failure, or multiple system failures. Witness Air France's pilots unable to cope with airspeed loss- something every student pilot learns to cope with- , and so they flew their perfectly functional jet into the sea.
What does this mean in a car with just one display? Well, the stakes are far lower than in an airplane for sure. But single point failures are going to put Model 3's onto flatbeds for sure. That might be an annoyance, or something more than an annoyance. It surely is not conservative design, and I think it will prove to be a " tail that wags the dog" mistake where a design directive- just one screen!- ends up causing a lot of collateral damage down the road.
Or alongside the road.
