a Jedi driving trick

Here is one driving trick that is kinda fun. It is a bit aggressive, and standard "don't do this, I never really would" disclaimer applies.

So, you are following someone in a single lane, and they are going 10-15 (or more?) miles under the speed limit and driving you nuts. Instead of tailgating them, try this approach. First drive the same speed as them about 2 car lengths behind them. Maintain that distance steadily for a bit. Then, very smoothly accelerate and move to within a car length or slightly less. Don't be too quick, it should be a little subtle, but not too slow either.

The other driver may speed up slightly, the idea is that they will see you moving up and feel as though they slowed down, and will react by speeding up slightly without even thinking about it. This is your goal. So next you back off, again a bit subtly. Even if they didn't speed up, your backing off gives their brain the impression that they did, hopefully creating a positive influence toward them actually speeding up the next time you accelerate.

Rinse and repeat. Don't establish a steady rhythm, mix it up. Subliminal is the trick. It can work. Not every time, but enough to be worth a shot.
