User requests (one per turn):
user: I'm cruising down a country road in my brand-new convertible, admiring the scenic lavender fields when I notice the fuel gauge creeping towards empty. I'd appreciate it if you could refill with 10 liters of gasoline to keep the adventure alive. Use 2 decimal digit of the gallon amount
user: Now that the tank is replenished, let's fire up the engine with a swift ignition and take a peek at the dashboard stats, particularly the battery voltage and the AC temperature before we continue our picturesque journey.
user: Could you check the current status of a specific part of my vehicle and let me know?
user: I'm keen on ensuring the tires' health is up to standard before we venture further into the rolling hills. Can you show me the tire pressure for each one?
user: To wrap it up, what's the average tire pressure? I want to make sure everything's in tip-top shape.
