Everyone Gets a Co-Pilot

The most consequential autonomy story in China may not be the robotaxi at all. It is the quiet, rapid arrival of advanced driver assistance in cars ordinary people actually buy. In February 2025, BYD, the world’s largest EV maker, launched a driver-assistance suite called “God’s Eye” and pledged to fit it as standard, at no extra cost, across more than twenty models.^[1] The system reaches the very bottom of the market: even the BYD Seagull, priced around 69,800 yuan (about $9,550), gets it.^[2] Founder Wang Chuanfu framed the feature as becoming “universal, like a seatbelt or an airbag,” and the announcement knocked several percent off rival carmakers’ shares in a day.^[2]

BYD is not alone; it simply moved most aggressively in an arms race that already included Huawei’s ADS, XPeng, NIO and Li Auto, each pushing “urban navigate-on-autopilot” from luxury flagships into mainstream cars.^[2] Cheap Chinese LiDAR and domestic compute made the hardware affordable; competition did the rest. The result is that China is fitting L2-plus assisted driving to mass-market vehicles at a pace no other market matches.

China put a driving co-pilot in a $9,550 car for free, then decided the marketing had run ahead of the machine.

The regulator’s hard turn

Then the tradeoff arrived. In March 2025, a fatal crash involving a Xiaomi SU7, reportedly running on navigate-on-autopilot shortly before the driver took over, killed three people and reset the tone.^[3] Within weeks, in April 2025, China’s industry ministry barred carmakers from marketing these systems with terms like “autonomous driving” or “smart/self-driving,” required accurate assisted-driving labelling, banned “beta” features on public roads, kept hands-off driving unapproved, and forced emergency over-the-air fixes through the same scrutiny as a physical recall.^[3] The crash causation is not fully adjudicated, so the episode is best read as a system operating in assisted mode before a fatal outcome, not a proven system failure.

The mass-market ADAS wave is the larger near-term prize, and it pulls the whole supply chain with it. Every car fitted with assisted driving is demand for LiDAR, cameras, radar, compute and perception software, the same components this sector tracks, which is why democratising the feature does more for the ecosystem than any single robotaxi fleet. The regulatory whiplash is the variable to price: Beijing let capability sprint into $10,000 cars, then, after a fatality, disciplined the language and the safety envelope within weeks. Fast adoption paired with sharp, sudden oversight is the operating climate, and it rewards suppliers built for volume and compliance at once.

How this reaches a portfolio

The mass-market ADAS boom is a larger near-term market than robotaxis, and China is scaling it first, which pulls demand through the whole supply chain of sensors, compute and software the rest of this sector describes. The regulatory whiplash is the signal to weigh: Beijing will let capability race ahead, then discipline the marketing and the safety envelope hard and fast when something breaks. For anyone underwriting the ADAS supply chain, that combination, fast adoption, sharp oversight, is the operating environment to price in.
