car ninja 

A person who displays incredible and/or aggressive driving skills. This may include but is not limited to speeding, cornering, parking, or otherwise steering the vehicle with a swiftness and death defying nature that cause other motorists to cower in fear.

Wearing all black and carring shurikens while driving are not necessary to be a car ninja but they make ya look damn cool...and probably highly arrest-able.

Driver - See that parking space. Bam! I there. That other car in front? ZOOM. Ha! I cut him off like that! I am a car ninja.
Passenger - {meekly} I'd like to get out now.

Ninja Car

A vehicle that appears out of thin air, completely parallel to your car, the moment you start to change lane.

I tried to change lane, looked in the mirrors and everything, but as soon as I started, a ninja car suddenly WAS there and blocked me. It came from nowhere!
