Have you ever seen behind the dashboard of a modern car? It's a monstrous tangle of wiring, with inch-thick cabling bundles and dozens or hundreds of connectors. A touchscreen-centric interface like the Tesla Model 3 could easily save several kilos of cables and connectors. There's a huge amount of labour involved in installing all that wiring and a huge number of opportunities for failure.

I support Mazda's efforts here, but there are compelling commercial and engineering reasons to go in the other direction.
