   Odd, the usual multiple-left-turn failures that I see (and we have a lot   
   of double left turn lanes around here, so this is sadly common) are from   
   a driver in either lane simply turning in too early.  Either the guy in   
   the outside lane will pinch the guy in the inside lane, or the guy in   
   the inside lane will realize when he's most of the way through his turn   
   that he needs to slow and turn more sharply or else run wide into the   
   right lane on the cross street.   
      
   The "right way" to do it is to visualize a quarter circle arc from the   
   lane you're in to the lane you're going to end up in (leftmost lane if   
   you're in the inside lane, next one to the right for the outside lane)   
   ending at wherever the "intersection" turns into just plain old "road."   
     If you draw it out on paper you will see that that means possibly   
   going perfectly straight across a couple lanes of cross traffic that's   
   going from your left to right - but try following that line, or if   
   you're familiar with  racing lines and apexes etc. modify it slightly,   
   just remember that early apexing will kill you not only on the track but   
   when making slow speed turns on the street.  I never pinch the guy in   
   the inside lane, and (if I do it right) I never have to slow and make a   
   correction to keep from running wide.  I'm on the power and down the   
   road while the guy that turned in early is behind me :)  And there's   
   nothing that pisses off the average driver more than seeing the guy   
   who's apparently driving slowly (but smoothly) somehow magically end up   
   in front of him!   
      
   I tend to just stick with the quarter circle line and stay in the middle   
   of my imaginary "lane" - using a more racing type line I'd end up going   
   out-in-out and more often than not another driver's trying to occupy   
   part of my "lane" anyway so it's not worth the potential risk to get my   
   exit speed up by some fraction of a MPH.   
      
   Now, the question is, how do you convince other people that this is the   
   right way to do it, even though you know deep down inside that it   
   actually works and works well?  *shrug* set a good example I guess and   
   drive well consistently.  Doesn't really work, but it's the best idea I   
   have.  (oh, and if someone actually *asks* explain it to them, but that   
   is vanishingly rare.)   
      
   When this *doesn't* work is the rare case that the road you're on has   
   the same number of lanes but is substantially wider than the road you're   
   turning onto - because the road you're on has a wider median, or has   
   turn lanes where the road you're turning onto doesn't - in that case you   
   may have to deviate from the "ideal" line to keep from interfering with   
   oncoming left turning traffic, turn in a little earlier and make a   
   shallower turn with a sharper correction at the end.   
      
   Then, of course, you have the morons that just turn into the wrong lane   
   altogether... or the guy RTORing onto a 3+ lane street while you have a   
   left turn arrow that gets all flustered because he can't figure out that   
   he needs to stay in the right lane and then change to the left once he's   
   out of the intersection area, and can't just turn into any damn lane he   
   wants...
