If you're referring to private automobile, than that is far from any type of privately funded mode of transportation. In fact its probably the opposite, when you consider that the last several years we've had to bail out the Highway Trust Fund with several billion dollars each year. In fact $63 billion over the last two years and that came from your income tax, not your gas tax.

Plus how exactly is giving more transportation choices stopping people from moving freely about the country? Is having more public transit options such as rail, buses, flying, driving, make us less mobile? I should think not.
