People are Strange...

I'm trying to understand what goes on in the minds of some people on the road(futile, I know). I have a 63 mile one-way commute, so I occasionally see some weird stuff. Yesterday on the way home on westbound I-94, I'm in the fast lane doing about 80. I see a lady coming up behind me going faster, so I move over to let her go by. She doesn't go by - she slows down. Since I'm now coming up on traffic, I move back into the left lane. This chick speeds up and sits on my bumper. I figured ok, she's just being weird, and doesn't want to pass. With the ebb and flow of the traffic, we both have to slow down and speed up. But she always catches up to less than a car length behind me, no matter what speed. We come up on slower traffic in the fast lane and she goes to the right lane to get around. Unfortunately, she couldn't complete the move before she's forced to slow down, so now she gets behind me again. Since she now seems to want to pass, I clear over when I get a chance. This time it takes a little longer for me to find a break in traffic, but again I move over to let her pass. You guessed it - she slows to stay behind me. I move back into the fast lane to get around slower traffic and she's right behind me again, now at 85. This 'dance occured one or two more times. She never passed me until she got to her exit. What the HELL...?
