I agree with Tom, always "invert" in code as the wiring and terminals are marked so that you can always connect them consistently no matter who replaces the motor or motor controller. In theory there is a much larger pool of people who might replace those items vs the pool of people who might change the code.

Much safer to comment the code that L drive motors are "inverted" than to make sure that everyone who could ever possibly change a motor, including people on other teams who may be lending a hand in the heat of the moment between finals rounds that the L drive motors are to be hooked red to (-) and black to (+). It could be particularly disastrous should you have a dual motor system and to wire one of the motors backwards so that they are fighting each other. Best case secnario your robot doesn't function, worst case you let the magic smoke out of both motors or motor controllers and now you've got two to change before the next round.
