If, as you say, the property is fully landlocked and this driveway is your acces to a country road, you should be able to get an easement (called an "easement by prescription") to allow you to use/access it, but will have to file a lawsuit against the other property owner to get it. Only a court can create an easement against a property owner's will, and you can't get the courts involved without a lawsuit. To explore this option, consult with a real estate attorney.
