Everyone is allowed to have 2 people in their house OR one bubble family. If this person is that to you, then yes I would feel you can go for a car ride without a mask. Vaccination is not relevant as the rules have not changed for those vaccinated.
If they are not your 2 people or bubble family then no. If they need a ride to a medical apt etc., you could transport them, wearing a mask and distancing as you could in the car.
