I am well aware of the auto dimming side view mirrors. My previous German luxury SUV had them and I loved them. Just surprising that Mazda, who is trying to compete with the features of luxury brands, would not have these inexpensive feature on a car that has all the safety features. Just looking for something to calm down the glare.Apparently you have never had this feature on your vehicle before. My 2000 BMW 528i has this feature and I like it. Yeah it's not as useful as auto-dimming inner rear-view mirror, but it's a legit useful feature to have.
It's not doing "auto-dimming" like the inner mirror, but it's also different from putting on some tint film. You just have to experience it to know.
