I've been opposed to mirrors because I was told 1) they distract you from the more important traffic and terrain in front of you and 2) you get into the habit of relying on them when you should be scanning. I still believe what I was told but I will add 3) on rural roads they can save your (or your daughter's) life.

Based on this thread I'm getting the Take A Look mirror. I'll order an extra one for my daughter, but I will need to encourage her to get in the habit of wearing either sunglasses or goggles. She should wear eye protection anyway.

It'll be very easy to convince her of that. She's highly safety conscious right now. Last night she said to her dad, "The speed limit is 70 mph.' (He was driving 75 mph.) "The speed limit is there for our safety." He slowed down to 70.
