We've seen a fair number of so-called rear-looking safety systems of dubious merit in our time. Now Drivaware is offering what it claims to be the world's first "active blind spot exposure system" with their LaneFX product. It's quite simple really, as long as your car is equipped with powered mirrors, then flipping on the turn-signal causes the side-mirror to sweep and expose your blind spot allowing you to safely execute your lane change without ever moving the ol' noodle. So go ahead and layout the $296 for the deluxe model.
