The hud as you call it is not a safety critical part of the car in Teslas. You can reboot it while driving without effecting the car. The self driving computer is separate and has full redundancy to the point of having two processors running redundant code. There is a reason Tesla’s are consistently rated as the safest cars on the road with low probability of being involved in an accident and lowest probability of injury when an accident does happen.

2 Processors? What happens with majority vote if they disagree? (or maybe they wanted to avoid a 'minority report' situation :-)). But honestly do you know what they do? Although since it is not flying, probably some red indicator will light up. And maybe a stopping maneuver.

Apparently they just try again:

"Each chip makes its own assessment of what the car should do next. The computer compares the two assessments, and if the chips agree, the car takes the action. If the chips disagree, the car just throws away that frame of video data and tries again, Venkataramanan said."

The self driving computer was discussed in some detail at their 2019 Autonomy Day event.

Fail safety doesn’t mean anything, if the decisions it makes is bad, like thinking a plastic bag is a solid object on the road, or simply forgetting where the lane is over a distance and swerving into oncoming traffic..
