The mood lighting is not the main problem, cutting back and forth between two completely different viewpoints (feet- and eye-level) is. Especially in a 360 video where you are trying to transport the feeling that the driver is basically sitting it truck, this seems very counter-productive to your point.
Theoretically, yes. But I'd be concerned about fatigue and stress of having a current-gen headset on people all day long. Seems like 3D screens might be a better solution until headsets get lighter / more comfortable.
