Car Wash, Part Three: The AI Said Walk

In early 2026, variants of a prompt about a nearby car wash spread online after some assistants recommended walking instead of taking the car. This is neither the tokenisation failure from the strawberry post nor the grounding failure from the rainy-day post. It is a pragmatic inference failure: the response followed the travel wording but missed the likely purpose of the trip, assigning its advice to the wrong interpretation of the question. A third and more subtle failure mode, with Grice as the theoretical handle.

Should I Drive to the Car Wash? On Grounding and a Different Kind of LLM Failure

A viral video this month showed an AI assistant confidently answering “should I go to the car wash today?” without knowing it was raining outside. The internet found it funny.

What the system lacked was access to the state of the world the question was about.

Three Rs in Strawberry: What the Viral Counting Test Actually Reveals

The viral “three Rs in strawberry” test exposes a real mismatch between token-level input and character-level operations. It does not, by itself, identify one tokenizer boundary or explain any particular model response.

Please Stop Saying the Sun Is on Fire

In September 2020 I gave a teacher training talk on stellar formation and the misconceptions students bring into class. The misconception list was long enough to be its own document. Here it is, with commentary. Includes: the Sun as a heat-planet, gravity that only works when things move, metals that always existed, and the obligatory complaint about quantum leaps.
