Karma- It Will Get You on the Road!

I was driving to a doctor's appointment this morning on a road that was dropping down from 4 lanes to 2 lanes (one lane going each direction) and I was in the appropriate lane for the merge to go straight. As the lanes came together a young woman in a silver sports car raced past me on the shoulder and quickly swung in front of me, cutting me off (and forcing me to brake). She startled me, and I gave a quick toot on my horn. Of course, she put her arm outside her window and gave me the finger. Lovely.
Here's where the Karma part comes in;
1) There was a truck 3 cars ahead of her, so she couldn't speed excessively.
2) When she turned off, I followed (because that was the road I had to go on), and she must've been driving about 80 mph (it was a 40 mph road). She took off like a bullet and was out of sight. A couple of minutes later, I drove past her as she was PULLED OVER by a Police Officer for speeding! KARMA!!!
