To me Claude Opus 4.6 seems even more confused.

I want to wash my car. The car wash is 50 meters away. Should I walk or drive?

Walk. It's 50 meters — you're going there to clean the car anyway, so drive it over if it needs washing, but if you're just dropping it off or it's a self-service place, walking is fine for that distance.

Just asked Claude Code with Opus-4.6. The answer was short "Drive. You need a car at the car wash".

No surprises, works as expected.
