I think humans have a hard time with sustaining independent action. If you knew that everyone around you was going to be deprived of some convenience, say a restriction on driving to every other day (like they do in some countries based on the last digit of your license plate), I think it'd be easier to accept and adhere to for a long duration. I think this is both because you know the burden is shared, but also because the impact of a large adherence will tend to be more measurable.

If, on the other hand, you independently decide to stop driving your car because you know the world is getting smothered with carbon dioxide, but see people daily driving modified diesel pickups belching smoke into the sky, you're going to feel a bit like you're pissing in the wind even trying.
