I opened up a claude code session using opus-4.6 medium thinking.

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

Drive — you need the car at the car wash.

but it's so close

It is close, but you still need the car there to wash it! Drive it over, and enjoy the short 50-meter walk back if you want to stretch your legs while it's being cleaned.

I tried the "upside-down" cup question brought up in another comment in this thread, and it also nailed it:

Flip it upside down. The sealed top becomes the bottom (holding your drink), and the open bottom becomes the top you drink from.

IDK, maybe the web versions are not as good at logical reasoning as whatever they're using to power Claude code, or you were unlucky and I was lucky?
