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

User requests (one per turn):
user: I just returned to my vehicle, and it dawned on me that I may not have unlocked the doors yet. Would you assist in unlocking them all?
user: With every door now open, please proceed to fire up the engine; I need to ensure everything's in working order before hitting the road.
user: Fantastic! With the engine humming nicely, it’s time for my adventure. Could you adjust the cruise control to 65 mph and make sure we're keeping a prudent distance (100 meters) from the car in front?

Expected function call sequence:
VehicleControlAPI.displayCarStatus
VehicleControlAPI.lockDoors
VehicleControlAPI.startEngine
VehicleControlAPI.setCruiseControl
