agreed, I was trying to make a very similar point. I would love for technology like this to be available and improve the situation. I lament that we already have mountains of evidence that people will take advantage of the opportunity for misuse.
The specific HUDs that provide augmented reality of driving conditions are not available (that I know of), and that is what I would love to see. Not just an alternate instrument cluster, but something that can show obstacles through fog and rain, something that can highlight a heat source from a deer in the grass/woods, even GPS route guidance traffic updates without having to look all around.
The device locked to the car, for car-centric information is where this tech needs to come from. Unfortunately the business model dictates that this will be developed from outside of the auto industry, and therefore the information will be web/internet based, and lolcats is just as relevant as traffic.
TL;DR it isnt FUD, because there is no uncertainty.
