You guys will probably hate me for badmouthing the "darn" things, but I don't like what I saw so far.
The wife's '14 Corolla has one and I find it pretty well useless - its like watching a cartoon and I'm really not sure just what I'm looking at.
I've always relied on the mirrors and the "walk-around check", especially with kids in the neighborhood - ya know, EXPENSIVE toys and bikes left laying around and the little br.....darlings not being totally aware of their surroundings.
I don't think the cartoon camera would help me much so I make any kids aware that I'm about to pull out.
I agree a beeper is a lot better and parents should explain to kids what it is.
