Anyone who has ever driven a car will note that they have ~200 degree peripheral vision to observe things moving in front of you, while the limited FOV of your mirrors does not provide that for what's behind you.

Unless you really struggle with object permanence, a child somehow ending up in front of you without you seeing them is not a frequent occurrence, compared to one ending up behind you.

But yes, American cars are stupid big and should be smaller.
