BYD ADAS-equipped vehicles top 4.19 million; 245,500 sold in October

The scale of BYD's ADAS fleet is the real story here: a data engine of this size compounds, since more vehicles feed more driving data back into the system. That gives BYD an advantage less in hardware than in the iteration loop, where volume and daily mileage translate into faster refinement than rivals can match. Who it affects is the broader driver-assistance supply chain and competing automakers racing to close a data gap. Whether rivals can match this fleet-driven data advantage, or whether regulators and buyers start scrutinizing how that data is used, is the open question.
