Multi-turn tool-use scenario.
Tools involved: VehicleControlAPI

User requests (one per turn):
user: Hey there, I noticed that all of my car doors seem to have locked themselves up, and with my schedule being pretty tight today, I'm in quite a pinch. I could really use your help to get those doors unlocked. It'd be fantastic if you could also switch on the headlights. It's getting a bit darker out here than expected, and visibility's not great!

Expected function call sequence:
VehicleControlAPI.displayCarStatus
VehicleControlAPI.lockDoors
VehicleControlAPI.setHeadlights
