Personally, I disable it on a per-use basis, and not within Settings. And actually, my use case for per-use disabling is usually when I'm the driver: I turn on my car and then I pick up my phone to select some music - but I can't because the phone thinks I'm driving even though I'm parked. But I'm sure most people have it permanently disabled.
