Maybe I'm cognitively challenged but I have found that if I am driving & talking on B/Tooth neither the driving or conversation are getting my full attention.
Most calls I get while driving are work related, involve a problem & need me to concentrate on the solution, easier & safer to do while pulled over with a fag in my mouth.
I don't smoke in cars.
BTW I also talk to passengers very little while driving be it SWMBO, kids or someone else.
As for touch screens I don't use them while in motion either. Either the passenger does it or it can wait.
I much prefer pushing a button that I have used 100 times before & it's location & use has been memorized/automatic muscles memory.
Hence a D2 suits me.
To me, maybe due to some history, driving is a serious business & needs full attention.
