To clarify a bit, there are few override bar situations that are not triggered by [vehicleui]
One example is the quest
Mental Training: Speaking the Truth to Power
These override bars are not considered vehicles. They used to be triggered by [bonusbar:5], but now they are not. Also, these bars use the action ID's 157-162, not the new 133-138 range.
I have a character with that quest active just for testing purposes. Right now, on live, [bonusbar:5] works fine for it. On the beta, I have found no macro conditional that will fire when this specific type of override bar is shown.
