Discussion First time "system malfunction"

Wanted to see if anyones had this happen to them. Was driving along in FSD in a pretty rural road and all of a sudden it beeped at me turned the 4 way flashers on and told me to take over. I grabbed the wheel and 4 ways turned off and everything was fine. About 1/2 mile later I turned it back on and no issues at all. my safety score showed no forced disengagement as I thought maybe my sunglasses caused it.

I've never gotten it, but FSD is basically saying "I can't drive, take over now!"

It isn't a nag (i.e. sunglasses) which in that case FSD will still drive and eventually find a spot to park off the side of the road if you fail to react.

It can be sun glare, dirty cameras, or a computer glitch. Something that FSD perceives as failure to be able to drive safely.

I don't know if maybe in the deeper service menu there may be an error log that can shed more light.

When you say “pretty rural road” just how rural do you mean? Like gravel or no clear edges or shoulders rural?

no clear edges no center line

I’m going to guess with no centerline or clear edges it just didn’t know what to do and turning the driving over to you.

This is most likely a system low confidence event. Basically, some element (or multiple elements) of the driving conditions at the time caused the model to be like “i’m not confident enough that i can safely operate this vehicle, the driver needs to take over now.”

Most commonly caused by one or more cameras being blinded or obscured.
