Yo-Yo Tailgating

I hate being followed by a yo-yo. It's bad enough when someone is sitting on my tail, but I think it is worse when someone is constantly getting closer and farther away. This happened to me this morning. When someone is constantly close, I feel like they have to be hyper-vigilant to stay that close without hitting me. With the yo-yo, I get the feeling that the person is just not paying attention, speeding up and then slowing down again when the car gets really close, and could rear-end me at any time.
