Outcome
About 90 minutes from their destination, with the family wanting hot chocolate and coffee, Shiva Arunachalam asked the Grok integration in their Model Y to find the best Starbucks on the way, with the shortest detour, the right direction of travel and timing so drinks would be ready, and to adjust the route. Arunachalam says it picked the right store and re-routed cleanly; they placed the mobile order by hand in the Starbucks app, and the drinks were ready on arrival.

The source didn't share its exact prompt, so we wrote this from what it describes.
Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing or a rule below tells you to. Goal: Find the best stop for [WHAT WE WANT] on my current route with the smallest detour, and add it to the navigation. Fill in before running: - Where I'm heading: [DESTINATION] - What we want: [e.g. a coffee shop with hot chocolate] - How long a detour is OK: [MINUTES] Rules: - Only suggest places in my direction of travel. - Give the detour time for each option and pick the shortest. - Tell me when I'll arrive so I can order ahead. - Confirm before changing the route. - Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify. Output: The best stop, its detour time and arrival time, added to the route once I confirm. You'll know it worked when: we stop once, with minimal detour, and get back on the road quickly.

Planning a 13-day cross-country motorcycle ride for a year ahead, the poster asked Grok and ChatGPT for an initial route and itinerary.

But when asked to draw a map of the route it had described, ChatGPT produced one that the poster says gets worse the more you look at it, making them question whether the itinerary itself was accurate.
