I think designing better car integration with smartphones is probably a good (makeshift) solution to this problem ...
Apple car play and Android Auto have still long way to go to not make using them frustrating...
But honestly I Love the fact that Apple Car play totally blocks off texting from your phone while you're driving and Siri reads out your text out loud and forces you to reply by voice recognition...
Trouble is, this method is very flawed, very screwy, where any one of many factors can make the experience anywhere from frustrating, to borken.
1) some people have shitty, cheap mobile carriers in Canada that get poor reception, this totally effects Siri's listening quality/behavior in a negative way, since it needs to be online and connected.
2) Some cars are louder than others or if you have your window down, convertible etc. hard for your phone to hear you talk to it.
3) (No experience with Android Auto) but Carplay is super limited, no app for Whatsapp for it (as far as I know) or any other third party texting , messaging apps are not supported, but a solid design overhaul on these systems, would I think go a long way to curb people's addiction with their phones, while keeping their eyes and (most of their minds) on the road!
