Really Giant QR Code Historical Sights

To those of you who stop at historical markers along your path I apologize.  I don't think I've ever stopped and read one myself because I'm too busy trying to get the heck to were we're going.  I do think it would be cool however if historical sights had big qr codes that you could scan with your phone as you drove by at 75 mph.  Then you could learn all about your trip without stopping.  Or better yet have your GPS recognize where the historical sight are and read them to you as you pass.
