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

User requests (one per turn):
user: I've noticed that some of my car doors are slightly ajar while others seem to be securely locked. Would you be able to verify and make sure all doors are properly locked for safety?
user: I'm all set to start my drive. Would you initiate the engine's ignition in START mode?
user: Before setting off, I'm keen to ensure my tire pressures are as they should be. Could you provide an update on the current tire pressure status? If it's below 40, point me to nearest tire shop.
user: I'd appreciate it if you could send a quick message 'I am on my way to your place.' to my cousin updating them my status. If you need, my user id is USR001.
user: Ah I forget to mention, his user id is USR002.
