FSD runs red light when have sun glare

I doubt that a fetal (or fatal) collision will occur in this scenario unless you fail to wake up and push on the accelerator.

In big picture, fetal collision will happen when FSD misjudges the traffic lights (eg: seeing red as yellow). It’s a buying time now.

That's why the brake pedal overrides FSDb.
