The BBC nails it

It turns this gibberish from the report: "...a temporary loss of awareness of the driving task during a period of low workload, which possibly caused him to micro-sleep...It is also possible that when regaining awareness, the driver became confused about his location and direction of travel."

Into English:

"The driver of a tram which derailed in Croydon had probably dozed off moments before the fatal crash, an official report has found." https://www.gov.uk/government/news/report-182017-overturning-of-a-tram-at-sandilands-junction-croydon
