Outcome

On a family road trip through Germany, Austria, Italy, Croatia and Slovenia, a poster used ChatGPT and Grok as an on-the-go assistant: planning village visits, walks and beaches, finding fairly-priced safe parking, choosing local beers and wines, and answering first-time EV road-trip questions such as where to buy national vignettes online, road taxes and trip-time estimates.

ChatGPT, Grok

Prompt Recreated prompt

The source didn't share its exact prompt, so we wrote this from what it describes.

Before you start, ask me 1–3 short questions about anything important that's missing below. Keep them quick. Then do the task, checking in with me at the key points.

Goal: Be my on-the-road helper for a multi-country driving trip: parking, tolls, charging and day plans.

What I can give you (ask for whatever's missing):
- Countries and route
- Car type (EV or not) and range
- Where we're staying each night
- What we like to do

Rules:
- For each country, tell me the official way to buy road vignettes or pay tolls, with the official site.
- Suggest parking near each stop with price and safety notes.
- Estimate drive time including charging stops.
- Keep day plans short and realistic.
- If a site asks for a login, a CAPTCHA or payment details, stop and hand control back to me.
- Ask for my OK before you pay, book, send, submit or cancel anything.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: A per-country checklist (tolls, rules, charging) and day ideas with parking.

You'll know it worked when: we have every vignette before crossing a border and never circle for parking.

- Buy vignettes only from official government sites; many lookalike resellers charge extra.

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.

    A traveller planned a Hong Kong trip mainly with Gemini, using Grok and ChatGPT as extras, to organise locations, build itineraries, make packing lists and turn store addresses into Google Maps links. The traveller says routes were logical and personalised, but the AIs sometimes produced convincing addresses that didn't exist, and got names, opening hours or whether shops were still open wrong. Next time they'd verify every important detail on maps and official sites.
