I would like to travel with my wife and kids.

It is insane to me that we are coming up with these impractical user interfaces with implausible limited use cases, when... we had interface that works! I'm refusing to let go of my aging Subaru, because any rental I've tried is impossible to drive without taking your eyes off the road or a myriad other safety and practicality compromises

I'd be interested to see human factors research to see if it helps. Still, if you've got kids in the back seat who are asleep and there's background road noise from a highway, you don't want to yell "Carbot, turn down the A/C". Turning a knob isn't that hard.

"Turn on wipers"

"Playing weezer"

It might be good if voice control was perfect but it'a long way from that and still offers little benefit over buttons and knobs.

They're great if you operate your car in complete silence. Personally I'm usually listening to something.

In most situations, I find voice commands to be very annoying and inconvenient. Particularly in a car.

Plus, given that most voice recognition is done in the cloud these days, if something has voice control then I am immediately very suspicious of it.
