No, I don't think it's realistic to expect everyone to make drastic changes to their transportation habits. In many places, public transport isn't reliable or even available, so people have no choice but to drive. Some families or workers really depend on their cars. Also, making big changes can be costly and disruptive. I think even small improvements, like carpooling, using cleaner fuels, or upgrading to more efficient vehicles, can make a positive difference without turning people's lives upside down.
