Developers of self-driving cars are amping up criticism of a California reporting requirement on test data, saying the data could mislead, as the state prepares to release the latest results for 2019.

Companies such as General Motors Co's Cruise and startup Aurora have said the metric, called disengagements, is not an accurate or relevant way to measure their technical progress, even though it is widely used to do just that.
