Sitting/idling through the Squirrel Hill tunnel leaving work today, I was in front of some chucklehead in some stooped BMW X thing with a pair of twin suns mounted on the front. First I was glad I have a 2004 with dimming rear mirror, then as we got in farther and darker, it was still too damn bright. So I put up the spoiler and it was perfect height to block the searchlights behind me.
