Does not sound like you have ever been anywhere near a combat situation. You don't know who is going to need to be able to drive something at the drop of a hat

Does not sound like you have ever been anywhere near a combat situation. You don't know who is going to need to be able to drive something at the drop of a hat. And the more fiddly and complicated something gets, the more likely it is to fail because of either technological or UX/human reasons in stressful situations. This would cost lives.
