Nothing is more irritating when you're driving at night than getting some jackasses brights shone in your face from your rearview mirror. Well, I guess there are lots of other, probably more irritating things that could happen to you while driving at night, but bear with me. I'm trying to make a point here.
What I was getting at was that there's some fancy new mirrors out there that automatically adjust when an idiot in a Hummer tailgates you with his high beams on, darkening so you don't get blinded and plow into a gaggle of orphan schoolchildren on a fun run. The mirrors, created by Gentex, are an option on the new Audi TT Coupe. And really, if you're buying a car that fancy why skimp on the bonus features? That's the whole point of buying an ostentatious car like that: showing off the cool features to people you sucker into riding around with you.
