G1 is best for: Tinkerers, developers, and early adopters who want hardware in hand now. Iron is best for: Tracking whether the Tesla playbook works twice — this time from Guangzhou.
Our scoring weighs five factors: autonomous capability, independent verification (third-party evidence scores higher than manufacturer claims), commercial deployment scale, price-to-capability ratio, and real-world availability today.
