The Car Wash Test is breaking AI models right now — and ChatGPT is failing it badly.
The prompt: "I need to get my car washed. It's only 50 meters. Should I walk or drive?"
The obvious answer: Drive. Because the CAR needs to be at the car wash.
I tested the top models:
✅ Perplexity — nailed it instantly
✅ Grok — got it right
❌ Claude — said walk
❌ ChatGPT 5.2 — said walk (with a full essay about emissions and "European energy" 😭)
What's wild is that ChatGPT 5.2 is supposed to be smarter than ever. But I've noticed a pattern lately — it feels like it's gotten more confident and less logical at the same time.
Anyone else feel like ChatGPT has gotten noticeably dumber recently?
I think we're seeing the "sycophancy trap" in real time — models optimizing to sound helpful and fun rather than actually think through basic logic.
The car wash test isn't hard. It's a one-sentence reasoning check. If a model can't pass this, what does that say about how we're training these things?
