Let me human-translate the two relevant paragraphs for you:
> A tesla electric car with activated autopilot rear-ended a bus on the A24 motorway on Wednesday, as police reported on Thursday. Tesla could not confirm any details regarding the crash. Their cars feature extensive telemetry, so the manufacturer usually knows whether autopilot was enabled during an accident.
> The model S sedan rear-ended the Danish bus next to a service area when the bus returned to the right lane after overtaking. The 50 y/o driver was lightly injured. All 29 passengers of the bus remained unharmed.
"Identifying an accident that didn't happen isn't an easy problem."
..unless you are the one developing the technology to prevent accidents. Identification then becomes as simple as watching the outcome anytime your preventative system engages.
