I think it has nothing to do with laziness, while this may be hard to grasp for many, GT is a game, designed for fun. Not wanting to spend hours and hours of your life just to drive the car you want is not lazy. The GT mode was so pointlessly lackluster that I would blame no one for skipping it. I hate when people turn simple questions into ethical issues. Reminds me of when duping was the thing, people were acting defrauded and violated because someone got an expensive car easily.
