Re: 'The capacitive buttons ... make it vastly easier to operate the phone in the car'

You appear to have the impression that it's illegal to use a mobile phone in the car. It isn't. It's illegal to use a *hand-held* mobile phone in the car. Mounted on a cradle, left on the dashboard, sat in a pocket and controlled by your shiny watch - all of these are legal.
As an example, my Moto Z sits on the dashboard connected to the car stereo. If I want to listen to music I reach out and gently caress the fingerprint sensor (which I can do without looking at the phone), then say "OK Google, play Bon Jovi". And it does.
Perfectly legal and doesn't require looking at the phone or driving in an autonomous vehicle.
