BYD announced on May 28 that it will cover all financial losses from crashes that occur while its urban self-driving feature is active in China. The coverage includes repairs to the owner's car, damage to third-party property, and personal injury costs. There is no payout cap, no separate insurance policy needed, and it will not affect the driver's future premiums.
That last detail matters more than it sounds. Every other carmaker selling assisted driving technology today puts the legal and financial risk squarely on the driver. The car company markets the system, charges for it, and then walks away if something goes wrong.
BYD's own owner manual equivalent says the opposite. If the system causes a crash while being used correctly, BYD pays. That is a fundamental change in who owns the risk.
The pricing context makes this even sharper. BYD's assisted driving package costs around 12,000 yuan, roughly $1,770, as a one-off purchase. Tesla's equivalent in China costs 64,000 yuan, around $9,400, with no subscription option. So BYD is offering uncapped crash liability on a system priced at roughly one-fifth of what Tesla charges for software that still leaves the driver responsible for everything.
BYD already ran this experiment with its automatic parking feature. When it offered the same liability guarantee for parking in July 2025, actual usage of that feature jumped from 21% to 93%. Fear was the barrier, not technology. Remove the financial risk from the driver, and they use the system. More use generates more driving data. More data makes the system better. This is deliberate strategy, not charity.
The comparison to Tesla is impossible to ignore. In September 2025, a Miami jury awarded $329 million in damages after finding Tesla's Autopilot system defective in a fatal crash. That was the first time a jury had found the system itself defective, not just the driver. Tesla contested the verdict. Meanwhile, Tesla's own manual states clearly that the driver is responsible for the vehicle's speed and control at all times, whether the self-driving software is on or not.
BYD has 3.15 million vehicles on the road collecting assisted driving data, generating around 200 million kilometres of driving information per day. That fleet scale is what makes the liability offer financially credible. The company is not guessing. It has enough real-world data to make a reasonable bet on the system's performance.
For anyone in the insurance or fleet management business, the direction here is clear. Bank of America analysts noted that as self-driving vehicles become more common, liability in accidents will gradually shift from individual drivers to automakers and software developers. BYD is not waiting for that shift. It is accelerating it.
The practical limits are real: this coverage is only available in China, only lasts one year, and only applies when the driver uses the system correctly. The definition of "correctly" will be decided by BYD when a claim is reviewed, which is a meaningful catch. But none of that changes the underlying signal.
The question of who pays when a car's software causes a crash has been hanging over the entire industry for years. BYD just gave a public, contractual answer. Every other carmaker now has to decide whether to follow or explain why they will not.
