It's worse, not answering with bullshit seems it could lead to negative results. If the real reason I would love working at company X is because the commute is 1/2 the other equal choices instead of making the world a better place, I won't admit it because 1) it makes me sound banal, and 2) in prisoners dilemma style I expect other candidates are bullshitting and I would be at a disadvantage.
"I believe that work life balance is key for happy people and happy people deliver better results. It so happens that working here with this company would allow me to cut my commute, providing better work life balance, allowing me to provide even better results than I already do today."
