From a local news station ABC7 WJLA:

A woman is dead after a crash in Aspen Hill, Maryland Monday afternoon, according to Montgomery County Fire and Rescue officials.

Crews said they responded to the intersection of Layhill Road and Bell Pre Road around 2:34 p.m. for the report of a two-car collision.

Given side impact on the driver’s side, it appears like with the recent Hong Kong case the Tesla ran a traffic signal (or… the other car did, which seems far less likely).

Update: Left turn details released.

Police stated she was driving a Subaru Outback, making a left turn from northbound Layhill Road onto westbound Bel Pre Road when she collided with a driver in a Tesla Model Y who was going southbound on Layhill Road.
