A cottage industry has emerged on Chinese e-commerce platforms selling tiny plastic doll heads designed to trick Tesla’s cabin camera into thinking a driver is paying attention. The devices cost as little as $20 to $50.

The products — marketed as “travel companions” and “dashboard decorations” — represent the latest and most absurd escalation in the arms race between Tesla’s driver monitoring safeguards and people determined to defeat them. It’s also incredibly dangerous and irresponsible.
