Impatient nasty aggressive drivers

We have a trend with drivers around here that seem to think as long as they get in front of you, if you hit them it's your fault. You know the type. Your cruising down the street coming up on an intersection or a parking lot. The person will pull out of the lot or sidestreet at breakneck speed and into your lane (no matter which lane you're in) and let off the gas. Or they will hurry up and then change lanes in front of you and let off the gas like they forgot where they were going.

I call it the "Idle Wobble".
