Why isn't there a driver's license that doesn't allow passengers? There is not enough demand for such a thing. If one is unable to say no, the other option would be to get a vehicle that only facilitates one occupant. e.g. motorcycle, moped, bicycle, e-bike, tractor, small street legal side-by-side, Japanese mini-truck if your state allows them, utility truck with equipment occupying the one passenger seat, etc...
