Obama will just tax you more and tell you to move to an urban ghetto and ride a bus!
Obama is not the POTUS and the POTUS does not make law.
Look at how much this will change our habits. If suddenly water was an issue (and it is in the western US where I live), people will change. My water bill runs $800/mo in the summer on the house I just bought. Guess what? I am going to have a landscaping firm change things.
People move on market forces and that is great. Fuel prices spur change and that change will be good.
