How do you deal with an overbearing parent?

Unfortunately I still live home. I am saving for a house and definitely want to move out but everything is too expensive. Next week I have to take half day for a doctors appointment at the local hospital. The hospital is about 5-8 minutes from my job. But my overbearing mother insists on dropping me off at work so she can pick me up and take me to the appointment because she says I won’t find a parking spot. I told her I would be fine but she keeps insisting. What do you do? It’s embarrassing to be dropped off and picked up at work like that.
