If there are enough buttons, yes.

Toyota makes 10 million cars a year.

Another angle is that you can add/remove/relabel software buttons later. Hardware decisions are much more final.

When I worked at Toyota (well, NUMMI) in the '90s, the engineers from Toyota Japan that told me: "I'd kill my mother to save $1 on each car produced." Yes, at Toyota's scale, $1/car is a lot of money.
