We all know that one person: you know, the one that is a HORRIBLE driver but no matter how many accidents they cause or tickets they get are still under the delusion that they are a good driver. Well an objective measure of their driving abilities may bring them back to Earth, where the skies are blue and a yellow light does not mean speed up. Simply start the Backseat Driver application and let it run while ol' Earnhardt is driving and it will give a real time readout of their abilities. Of course, this is for entertainment purposes only (as in, the look on their face when they get rated a "Madperson" sure is entertaining). The free version is ad supported while the PRO version is ad-free.
