I agree. I see people backing out relying on nothing but their mirrors and back up cam. Even with all the tech Subaru has I still turn my head to look. The tech is good but it's the other drivers I don't trust.I'd suggest not backing out blind but the system seems to be fairly cautious. Mine the other day alerted me of a walker on a sidewalk across the street who I saw, eventually, but didn't think he was anywhere near the kill zone at any point.
