Then why doesn’t CarPlay support Facebook, Twitter, Safari, or any other apps that require you to stare at the screen? I see a clear trend in which of my apps support CarPlay and which ones don’t. The audio apps all support it. Nothing else on my phone does except phone, messages, and maps.
My optimism says its just too new to Apple. It will grow as most everything is visual. But Car Play apps ,I feel, will just be for apps related to things people want to do will driving. Weather maps along the route, trip computers, Priceline.com, Expedia, etc are all good matches for CarPlay. So, what's the point of having a screen, having an instrument panel because all this stuff draws your attention off the road? Everything could be replaced by a voice, including the speedometer.
On the other hand, when I was in Seattle last July, I heard on local radio, that they were considering new traffic laws that would make it illegal to do anything except drive. Eating food, drinking, smoking, using a phone, even hands free would be outlawed because they have way too many accidents caused by these activities.
On my 2014 Escape the nav system disables address entry when in motion which is a real PIA. But a company called Lock Pic made a modification to these nav packages that temporarily disables this disabling. I installed one on my Ford Escape. My Honda nav system recognized the disdain for all these limits they voluntarily put in place and came up with a compromise. The address keyboard entry only works when the car is in park, but when moving, you still can do an address entry by speaking it with the voice prompt. Voice to text entry is the latest way for this stuff to work. This is not siri although with car play connected you have siri as well.
Personally, when we travel and need to use these features while driving, it's always done by the passenger, not the driver. But I recognize that those young drivers especially, those with very little driving experience are the biggest violators of texting, and surfing the internet, while eating smoking and drinking with loud music playing that are the ones causing most of the accidents.
Maybe technology will make it so the dash has two screens and only the passenger has access to apps and features that take your eyes off the road. Maybe these features are allowed for the driver only when using the lane keeping assist feature if it is so safe.
One of the big changes with iOS 11 was that iPhones now go into do not disturb mode automatically while you drive by default.
I think that is disabled on mine because it doesn't work.
