A Ford Mustang Mach-E using BlueCruise struck the rear of a stationary Honda CR-V in Texas, USA, resulting in the death of the 56-year-old Honda driver.

According to a preliminary report from the US National Highway Traffic Safety Administration (NTSB), the 44-year-old driver of the Mustang Mach-E had been traveling eastbound on Interstate 10 when he rear-ended a stationary Honda CRV. 

The 56-year-old Honda driver was killed in the crash.

'Based on data obtained from the vehicle, the driver had been operating the vehicle in BlueCruise mode before the crash,' the NTSB said. 

BlueCruise monitors road markings, speed signs and evolving traffic conditions to control steering, acceleration, braking and lane positioning, and to maintain safe and consistent distances to vehicles ahead. 

The incident raised concerns about the reliability and safety of BlueCruise.
