I wouldn't even go that far: It's less wires to run.
Yea; my cars interface has had 3 radical redesigns since I got it (which I mostly appreciate), but think of how much easier to build a Model 3 is when it foregoes 95% of a cars normal physical buttons for a single screen.
- marcosdumay 3y agoIt shouldn't be expensive to make an I2C smart-switch that allows you to place as many buttons as you want on a single set of 3 wires (or 4 if you want a simpler circuit).

- marcosdumay 3y agoHum, it's terminated with resistors on both sides, so the boxes need power. That makes it 4 wires. I imagine there's very little difference on cost between 3 or 4 wires. But the number of nodes described is not really compatible with making each button its own node.
