I believe sushi is trying to say e.g., ... someone merging on the hiway as he is doing the speed limit. Heck, even if he was to slow down, chances are the knucklehead behind him is not paying attention and going to slam on the brakes.

Some folks don't belong on the road... Others, well, they are too busy shaving, putting on lipstick, brushing hair, reading (yes reading), eating and CELL PHONES, etc...

Downriggin'
