A driver who consistently makes poor decisions and unsafe maneuvers while operating a vehicle. Someone who lacks common sense and quick reaction time while driving. A bit different from a castard.
That cartard just turned left from the right lane.

Cartard - definition: Someone who constantly argues about cars, but in turn, doesn't actually know anything about cars. A cartard's knowledge of cars usually comes from, but not limited to: useless home video footage on YouTube, trolling the Internet for more false information, a drunken uncle or relative that believes all cars should have 8 cylinders, as he crushes a beer can on his head, that's usually covered by a rebel flag bandana. WARNING: do not engage in automobile talk with a cartard, it is an uphill battle, if you are uncertain if you are in fact dealing with a cartard, look for for these tell tail signs. 1. Drives a turd for a daily driver 2. Asks to barrow money before trying to "talk shop". 3. Brags about a car that's owned by a family member. 4. Constantly throws specs and statistics the are irrelevant. 5. Jobless with a light scent of bong resin.
Dustin: "dude, that car is a piece of shit, it needs forged pistons before I'd even piss on it."
Kory: "Dustin, what are you talking about? You don't even have a license or a job, and the only car you've owned was a terd sandwhich, go smoke another bowl you fucking cartard!"
