My screen froze while on NOA/FSD. It was working so I let it continue until my upcoming exit ram just to see if it worked; I took over at the traffic light and end of exit ram. The whole thing was less than 2-3 minutes. That was a mistake. Once rebooted, I got one strike (first one) for not holding the steering wheel. So if this happens to you, take over FSD as soon as you can.
