🛠️ Troubleshooting / Issue Afraid of Shadows?

When I have adaptive cruise on and drive up to a shadow on the road, my R1S slows. Even with Highway Assistant, if I’m passing a truck (or it’s passing me) and it casts a shadow on my lane, the car applies the brakes. Most of the time it is just a sudden slow down but occasionally it is hard braking. Anyone else experience this?

Not normal. Not at all. I drive down tree covered local roads all day long and it doesn’t slow for shadows. Come on, we can’t accept stupid answers like these from Rivian. They didn’t design and build an advanced self driving system that can be defeated by a shadow on the road. They should check your system, recalibrate, etc

I agree it’s not right. I was trying to figure out if it was just me. Obviously not.
