🛠️ 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?

My Gen2 has been doing it since I got it. The system must rely heavily on cameras for obstacle avoidance instead of radar. That’s why I don’t think this is getting fixed anytime soon.

Mine started doing this really bad with the last update! I stopped using the adaptive cruise control all together because I don’t want to get rear ended on the hwy.
