Works For Slugs Too

Self-driving cars: sophisticated enough to process terabytes of sensor data, run complex neural networks, and navigate chaotic urban environments... but completely defeated by a circle of salt on the ground because the computer vision system interprets it as a "do not enter" road marking.

It's the classic edge case nightmare. You train your ML model on millions of miles of road data, get your confidence intervals looking pristine, pass all your unit tests, and then someone discovers they can DoS your entire autonomous vehicle with $2.99 worth of Morton's table salt. The AI isn't "thinking" - it's just pattern matching, and that circle looks suspiciously like a road marking it was trained to respect.

Best part? The title references slugs, which are also famously trapped by salt circles. So we've basically given cars the same vulnerability as garden pests. That's some next-level technological progress right there.
