Well it should definitely be able to recognize when you are on a train and not in a car base on gps and maps. Problem is it still doesn’t do that. But it is not a deal breaker. Too many other issues with iOS to care about this nonsense.
Running the GPS and the cellular connection constantly to check if you're currently on a train track is a great solution with no possible downsides. Come on Tim, you're passing up on some real genius engineering solutions right here on the Macrumors forums!

How does one COMPLETELY disable it. I have it set to Manually (I can't set it to when connected to car bluetooth, because well I don't want it when I'm driving), and it still keeps prompting me. The best was when it prompted me last night while I was sitting on my couch watching TV. How about an actual DISABLED option!
Manual is disabled. It won't go on under any circumstance other than you turning it on. It's not checking for Bluetooth. It's not checking your speed. It's not checking anything.
