The U.S. government’s road safety agency is again investigating Tesla’s “Full Self-Driving” system, this time after getting reports of crashes in low-visibility conditions, including one that killed a pedestrian.
The National Highway Traffic Safety Administration says in documents that it opened the probe on Thursday with the company reporting four crashes after Teslas entered areas of low visibility, including sun glare, fog and airborne dust.
In addition to the pedestrian’s death, another crash involved an injury, the agency said.
Investigators will look into the ability of “Full Self-Driving” to “detect and respond appropriately to reduced roadway visibility conditions, and if so, the contributing circumstances for these crashes.”
You can’t measure this, because it has drivers behind the wheel. Even if it did three “pedestrian-killing” mistakes every 10 miles, chances are the driver will catch every mistake per 10000 miles and not let it crash.
But on the other hand, if we were to measure every time the driver takes over the number would be artificially high - because we can’t predict the future and drivers are likely to be overcautious and take over even in circumstances that would have turned out OK.
The only way to do this IMO is by
