A warning from Dr phat Tony:
Reports are coming in of automobiles all over the country becoming self aware and rejecting the internal combustion engine to live a more eco friendly life....many experts believe that this sudden self-awareness was caused by the ever increasing size and memory of the computer controlling the fuel injection and the guilt of global warming. 
When asked why the cars are rejecting their combustion engine, the expert said, “Cause they’re probably gay and listen to the radio. All you ever here about now is global warming this, and carbon footprint that. I would feel bad to if everyone blamed me for destroying the world. I guess them fancy computers just don’t know what exaggeration is.” 
As reports still come in, it seems that a many of the cars were only able to make it a few feet away from where they left their engine. Unable to convert sunshine, rainbows, and children’s laughter into usable energy the cars have seemed to lose all power and erased whatever “self-awareness” they had gained.
