The side repeater camera was updated - the version on the left is the newer part which uses passive geometry to create airflow disturbance that better keep water off the lens while driving. No cost penalty, just pure vision improvement.

It's pretty wild to me how Tesla FSD sees things way early even when sunlight is directly hitting the camera. I couldn't see the car until the last moment because of the sun glare, but FSD handled that scenario like a champ. It just doesn’t struggle anymore in direct sunlight.
