Yep, it is frightening isn't it? You've got the far left and right lanes of traffic trying to weave around the middle fool who insists upon going 60 when you've just clearly passed a round sign which had 100 encircled in red...

If you're reading this, and you're one of these people... please get over in the far right lane if you're going to drive below the speed limit like that. Slowly and peacefully is fine for you, since it appears you've noplace to be, but we're not all so lucky. Going slower than the speed limit in the middle lane is a worse traffic hazard than the person going 150 in the far lane, IMHO.
