I bet its not as good as, say, an S8+.
I guarantee that is neither easier to see or easier to reach than the mount in my mini.
It amazes me how some people like you can get off on an impossible to really defend argumentative branch, just for the sake of argument. I think I recall 'arguing' with you just a few years ago how a phone like the s8 wasn't even possible! Now here you are with 'the future' in your hand.
OF COURSE the large 8" tablet-like screen in my car is much easier to see than *ANY* by compasison piddly size phone screen.
The point in a car is your eyes should be on the damn road and not fiddling with a phone screen. Its not even arguable a good modern touch screen in a vehicle is better than your tiny phone... its not there for you to obsess some nonsense minutia over the way people do with phones. You're DRIVING. its to deliver quick bits of information to you in the seconds of time you glance at it...
Of course a large modern dash screen does a better job of that than a small phone screen.
And sorry, NO it does not sound like you've set foot in a modern vehicle with a decent tablet sized touch screen.
But by all means, insist the opposite of easily observable reality. "Tiny screens are superior to large ones in a car!" Lol!
