A Ford Mustang Mach-E crashed into two parked vehicles near Philadelphia, resulting in the death of two drivers.

According to the US National Highway Traffic Safety Administration (NHTSA), which launched an investigation into the crash, the Mustang sport utility vehicle hit a parked Toyota Prius and rammed it into a Hyundai Elantra. 

Both drivers of the stationary cars were killed, with one reportedly outside their vehicle. The crash closed a section of the interstate I-95 highway for several hours. 

The NHTSA said the Ford may have been operating on its BlueCruise partially automated driving system. 

Introduced in 2021 and classified as a level 2 autonomous system, BlueCruse 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.
