Only if your car uses 1 HP to carry an average person, or 3 for a strong, motivated athlete, and you limit your trips to your bike range. Regular bike use where appropriate can also save huge amounts of energy associated with sedentary health care, and make it far easier to choose tasty, nutritious food without too many calories. There are also huge energy costs from manufacturing cars and building roads for them.
Nothing is zero-impact. Even farming organic food displaces nature, and usually reduces overall biomass.
