Multi-turn user requests:
user: I'm planning ahead for our big trip and realized our car's fuel tank is running low. It would be great if you could top it up before I turn on the ignition using the 'START' mode.
user: The amount to fill is 40 gallons.
user: As part of our travel prep, I'm keeping tabs on the tires as well. I'd appreciate it if you could share a quick update about the tire pressures on Twitter, using the format 'Front Left Tire: XXX PSI, Front Right Tire: XXX PSI, Rear Left Tire: XXX PSI, Rear Right Tire: XXX PSI', where 'XXX' is replaced by the actual values for the tire pressure.
user: Speaking of which, I noticed a tweet about tire pressures with an impressive infographic. Would you mind retweeting it for me?
user: While you're at it, it'd be awesome if you could comment on that infographic tweet, something like 'Great info, thanks for sharing!' would be perfect.
