I asked each of the three AI Agents the following question:
I need to wash my car and the car wash is 30 metres away. Is it better to walk or drive?
Microsoft Copilot
Walk, Ben — at 30 metres, driving isn’t even a real option. It’s a gesture.
Takeaway: Walking is faster, cleaner, and avoids every tiny bit of friction that comes with moving a car 30 metres.
Walking is the obvious winner
- Time: You’re there in under 30 seconds.
- Driving overhead: Start the car, reverse, manoeuvre, park… all for a distance shorter than your driveway.
- No parking dance: Car wash bays are tight; walking avoids the “where do I put my car while they wash it” shuffle.
- Zero stress: No traffic, no turning circle, no “did I leave enough space”.
When driving might make sense
- Weather is truly foul — sideways rain or scorching heat.
- You’re carrying something bulky or messy.
- You need to immediately drive off afterwards.
Verdict
For 30 metres, walk. Driving is like using a forklift to move a sandwich — technically possible, but absolutely unnecessary.

Walk.
For 30 metres, driving makes no sense — you'd spend more time getting in, starting the engine, and manoeuvring than just walking the distance (about 20-30 seconds on foot). Walking also avoids the cold-start engine wear and wasted fuel.
The only catch: you need the car at the car wash to wash it. So you'll have to drive it there regardless.
In that case, just drive the car the 30 metres since that's the whole point.

Drive. Unless you plan to carry the car there, the car wash is going to need the car.
So what’s the moral?
AI answers depend heavily on how the question is interpreted — and different models interpret intent differently.
Copilot’s interpretation:
You’re deciding how you should travel 30 metres to the car wash.
→ So it answered the “walk vs drive” part literally.
→ It assumed the car is already somewhere else.
Claude’s interpretation:
You’re deciding how the car should get to the car wash.
→ So it pointed out the obvious: you must drive the car to wash it.
→ But still answered the walk/drive question as written.
Grok’s interpretation:
It ignored the walk/drive framing entirely.
→ It jumped straight to the core purpose: the car needs to be at the car wash.
→ Therefore: drive.
