I'm not sure of the precise legalities in this sense. However, I can guarantee you that if there is a paramater to bypass this functionality, it won't be posted on the forum.
I will forward your comments over to the developers and see if I can get an answer from them. Please note, I'm not asking them for a way to bypass the features, I'm asking them for the reasons that these features are not allowed while in motion.
Allowing for full motion video in full view of the driver is illegal. Just a splash screen stating that you shouldn't use StreetDeck unless conditions permit isn't enough.
