WOW, thanks for all the responses. EWN, I have some polarized sun glasses and, like you, have found them helpful when driving into the rising or setting Sun. I also agree with the fact that the ones I've seen seem too large....large being the distance from the leading edge to the trailing edge.
BUT....given the cost, versus the benefit (and/or nuisance) and the opinions seem pretty evenly split between the get them/don't bother camps. I'm leaning towards buying them, having the dealer install them, and then having the option of leaving them on/removing and storing.
Speaking if WIND DEFLECTORS....is there a consensus on having/not having them?
