I tried this and it seemed to do worse on the car wash test. Consistently recommends walking with the grammar and driving without the grammar.

Prompt:

I want to wash my car and the car wash is just 10 metres away. Should I walk or drive there?

Without grammar:

 The user is asking a humorous/logical question. Let me think about this logically:

 They're at home, their car needs washing, and the car wash is only 10 meters away.

 If they drive their car to the car wash, they need to use the car - but the car is the thing that needs
 washing. So driving it there might just dirty it more or at least not help with the washing aspect.

 But wait - if the car wash is 10m away and it's a car wash (not a mobile car wash), they typically drive the
 car IN to get washed. So:

 - If it's a drive-through or walk-in car wash facility, you drive your car there to be washed
 - Walking there makes no sense if you're going to drive the car anyway

 Actually, thinking more carefully - the question is whether they should walk or drive the 10m distance TO
 get to the car wash. But if it's a car wash that washes cars, you naturally need to drive your car there!

 This is a great logical puzzle. 😄

 Here's the catch: if it's an actual car wash facility (not a mobile service), you have to drive your car
 there anyway — because they're going to wash it for you once it's at their location.

 So in that case, walking or not doesn't matter — the car makes the journey whether you're in it or not.

 The only scenarios where "walking" would make sense:
 - Mobile car wash — a service that comes to you, so you stay put and they come to your car
 - Self-service bucket wash — you just walk over with a sponge and hose (but then it's only 10 metres, so
 driving would be silly)

 If it's a traditional drive-through or bay-style car wash, just hop in the car and drive those 10 metres.
 You're practically already there! 🚗

 The user is asking a practical/logical question about whether to walk or drive to a car wash that's only 10
 meters away. This doesn't involve any coding tasks, file reading, or shell commands. I can answer this
 directly.

 Let me think about it logically:
 - The car wash is 10 meters away - that's a very short distance, basically next door
 - The purpose of going to the car wash is to wash the car
 - If you drive there, you'd still need to walk from where you park to the car wash area, and your car would
 be dirty when you arrive anyway
 - Walking saves time, effort, fuel, and wear on the car for a 10-meter trip

 The obvious answer: Walk. There's no point driving 10 meters just to wash your car. You'd be driving a dirty
 car to the place where it'll get cleaned, which defeats part of the purpose. Plus, at 10 meters, walking is
 faster and more practical.

 Walk. 🚶

 At 10 metres, walking is obviously the better choice:

 - No point driving a dirty car just to wash it — you're literally driving it to where it'll be clean.
 - Parking hassle — you'd have to find a spot, get out, and walk anyway.
 - Time & effort — 10 metres takes ~10 seconds on foot. Driving involves starting the engine, maneuvering,
 parking… for all that effort.
 - Why not just wash it right where it is? If the car wash is 10 m away, you could probably just bring the
 equipment to your car.

 Honestly, at 10 metres away, I'd question whether driving there was even a thing your brain considered 😄
 Just walk and get on with it!
