What happens when two Teslas with their latest and most sophisticated “collision avoidance” systems, marketed as such since at least 2016, are driving towards each other?

State police identified the victim as 21-year-old Alexis Ann Newcomb of Ashburnham, MA. […]

According to state police, the crash was a head-on collision between two Tesla Model Y vehicles. One was white and the other was gray.

Troopers said it appeared that the driver of the gray Tesla headed southbound when he crossed into the northbound lane and collided with the white Tesla, in which Newcomb was the passenger.

Clear skies, clear road… 2:50PM.
