It has been, the McDonalds app does all of this and reasonably well (over the Web, not Bluetooth).

They are targeting people who are driving and want to quickly get some food without leaving their car. Promoting app ordering for a drive-thru doesn't sit right - and can be dangerous if people feel they need to place their order while driving. I understand why they want this tech, because there will always be customer demand for voice ordering in drive-thrus. It's just sad that society is pushing so hard towards eliminating human interfaces and jobs, just so a few people can get a little richer.
