I think their intent is actually safety. They employ two touch interaction models: Flexible while not moving and simplified while driving. For instance, keyboard input becomes unavailable while moving and you must rely on Siri. I personally find it irritating, particularly when I am a passenger, but I get it.

Yeah, that's unfortunate considering you can have it do nearly all of that (download maps, navigate to business all while offline), except asking siri to do it for you.

My car pops up a dialog telling me (in a paragraph+) to pay attention while in semi-autopilot which I have to click "ok" on to get back to the map. It's very ironic, and extremely dangerous.
