Some people take the train, but that isn't always convenient, especially with strikes! Your boss doesn't care that you were 3 hours late due to a bus skipping out on work. Your paycheck cares a lot though.
Back in America, most people I knew lived and worked in the same general region/city. Perhaps this is a uniquely Dutch problem owing to the size of the country, but I don't see how they can reduce car usage without significantly more investment in public transportation. By the looks of the current state of the government, that's not going to happen anytime soon.
