There are large areas planned and there are enormous areas that are first come first served. Arriving day 2, without having a camp arranged, you will be in the first come first served spots. Burningman is designed to not run out of space, so no worries on that.
The smallest space assigned by the Burningman official placement planners is maybe 50x50-100, so not individual campers like you. Individual camps you join might place you at that level.
1. Prearrange to join a camp:
A they are placed at address - if they planned room for your vehicle, maybe there will be room, else park the car in the outer free space.
B they arrive before you and you have to find them - there is an art to that
2. Arrive and set up your own camp in he zone - if no one is there, ask adjacent camps if there are awake if they mind you setting up there
3. Walk in camping - car not by you. Designated quiet and remote spot between the airport and 2 o'clock.
