"High Driver Syndrome"
1. When one is under the influence of marijuana and operating a vehicle, not realizing how fast one is going they slow down and then realize they are going too fast so they speed back up. This process is often repeated.

2. When one speeds up because they realize they are going too slow and might get pulled over for going too slow. On the other hand, one feels like they are going too fast, so they slow down.
1. This guy keeps speeding up and slowing down, he must have HDS.

2. Dude, why do you keep speeding up and slowing down? Because I have HDS, man. I don't want to get pulled over for going 30mph in a 60mph zone.
