Nice diagram.
Its been the same basic idea for years but great to see younger drivers getting the information. Remember a quick head check is also a powerful tool unless you're a Jedi, but even then....
My M2 is my first car with Lane Departure warning. MY 2013 A8L did not have it nor blind spot warning. Our 2015 Q7 has the Blind spot warning but not the lane departure warning, go figure. It is VERY nice on that behemoth but I still turn my behemoth head and look! I was in a loaner A4 a few years ago which had the blind spot warning which I reproducibly confirmed and the dealer later confirmed DID NOT SEE SEMI-Trucks! VERY ODD. It saw other cars just fine, but if a Semi was there it saw NOTHING! So just as Luke Skywalker did, TURN OF THE NAVI COMPUTER and LOOK!
