Why wouldn't it be in-line with the road, you can't hold up your wrist in front of your face? You need both hands on your steering wheel at all times? How do you think stick-shift drivers drive their cars?
More importantly, is your car stereo/phone mount in front of your eyes while you drive, or somewhere at roughly the height of your sternum and off to the side? I don't see how you could say looking down and aside to your cell is safer, than just raising your wrist and flicking your eyes at the screen for a short moment. That's mighty weird.
Nobody gets fined for receiving texts to anything, anywhere. Except north korea (except they'd send you to a gulag - at best.)
Sending from a watch, sure. But why would people start sending texts while driving just because they wear a watch with that capability? That's friggin oddball reasoning.
It's not my "argument", my argument was that you shouldn't send texts while driving. Sadly not all human beings have a brain between their ears though, so a (depressingly large) number of them will anyway. Fact of life, I'm afraid.
Not really sure what you're on about, seriously. It's like you're going out of your way to find things to object about.
