A team of Dutch forensic researchers have decrypted Tesla’s data storage system, providing access to a trove of information that could be useful in crash investigations. (The news was first reported by Reuters.)

The team was investigating a crash involving a Tesla with Autopilot in use that had rear-ended another vehicle after it braked unexpectedly. Rather than seek the data from Tesla, the Dutch investigators chose to “reverse engineer” the company’s data logs in order to “objectively” assess them.

“These data contain a wealth of information for forensic investigators and traffic accident analysts and can help with a criminal investigation after a fatal traffic accident or an accident with injury,” Francis Hoogendijk, a digital investigator at the NFI, said in a statement.
