The benefit of buttons isn't in the response time, it's in the tactile feedback that makes it so you don't need 16ms response time. I heard it click, I felt it click, it clicked. If the thing I wanted to happen doesn't, it's because it's broken and not because I can't tell if I clicked the right spot on my iPad. Not having to take your eyes off the road in these cases is the benefit of buttons, and no improvement to response time in touch screens will fully solve that.

This isn't how tactile buttons in modern cars work. You're doing the same thing as pushing keys on a keyboard. The software can still be slow.

Turn the physical volume dial on a car with a slow Apple CarPlay interface and tell me how that works out for you.

Oh, it's too loud? But it takes 2 seconds for the software to respond due to lag and now you're fiddling with the volume button trying to not make it worse?

A physical button didn't fix that.

It does fix that because I dont have to look at it while I wait the 2 seconds. On a touch screen my finger will be slipping as the car is moving and have to constantly divert my eyes as I wait for the lag - even if its the same lag as a physical button.

You turn the physical dial, and regardless of the outcome, you know that your input was received by the HCI, so you don't need to wonder if you should try again.

If it worked, great; if not, oh well; no need to look at it and try again though. That's the benefit.

My car has this problem, only sometimes it takes a lot longer than two seconds.

The car when started always turns on the radio at the last volume the radio was on at, regardless of whether it was on when the car was turned off.

More than once, I have turned it on, and it was playing at full volume the Sirius FM ads, and would not lower the volume or turn off ( via the other physical buttons) for at least half a minute. I've done some damage to the volume button after that, and I have taken to just getting out of the car until the stereo responds.

I can operate physical buttons without taking my eyes off the road.

I know where the volume knob is and I can easily grab it and turn it without looking away. If it's slow to respond I can go again and dial it back down, without looking away. Or I can just keep my hand on the dial and spin it back a bit.

With a digital screen I can't leave my hand on it without continually pressing the input, and if I want to put the volume down I have to look and see where that button is.

A physical control absolutely fixes this

My car has this problem. I'm not sure if it's CarPlay specific or not because I've never played audio any other way.

[krsdcbl]

The issue is NOT the delay, it's having to look at the interface vs. being able to feel what I'm doing

[jojobas]

If only it was possible to adjust the volume without talking to the phone - heresy, I know. Having your phone decide how loud or quiet it should be playing is rather stupid anyway.

[seanmcdirmid]

A lot the knobs and buttons these days are digital anyways. So there is no real tactile feedback, since they are just activating some digital function anyways.

[tirpen]

The knob still exists as a physical thing between in your fingers. You can feel it turn, you feel how much you've turned it, you feel the little clicks if it has those, you feel if you turn it into an extreme position.

That's what tactile feedback is. It doesn't matter if the knob is connected to a digital or analog circuit. It has tactile feedback either way.
