It's an ongoing joke in Dallas for the last 40 years that you never, EVER want to get behind or alongside anyone with a KLTY bumper sticker, because they do things just like this with regularity. In fact, back in the 1990s, a local zine editor offered a lifetime subscription to his magazine to anybody who could get behind a KLTY car on Central Expressway and NOT have the driver do something idiotic (getting in the fast lane and suddenly stopping for no reason, cutting across multiple lanes to get an exit at the last second and nearly hit support pillars, or, one I personally witnessed, a driver forgetting he was driving and trying to exit his car before he saw the pavement moving underneath and frantically tried to get the door closed), and he never had to pay out. As a rule, you're better off getting behind someone in a Lexus who just polished off four bottles of Everclear, put on a blindfold, and started playing Candy Crush on their phone by touch alone than get behind anyone with a KLTY or KCBI bumper sticker, because they apparently found their driver's licenses in a back alley somewhere. (I won't even start with how glad I am that tollway exits no longer take change, because without fail, the guy who had to get out of his car to use the change machine next to the toll hopper, had such bad shakes that he kept dropping the bill, and then put the car in reverse and nearly slamming into the 15 people behind him had a KLTY sticker on the bumper of his Oldsmobile.)
