I noticed a couple days after buying my car that the headlights behind me turned dark blue when they got close to me, and when they backed off, it was normal again. I figured out our cars must have auto dim rearviews! hey, that's pretty cool Never mentions this on thw sitcker, any review, or anything. And what's more strange is that this is a nice option on many vehicles, but apperas to be standard with us! Anyone confirm this?
