Was she on something?

Cleaning up the end of a long police chase in Orange County, California... and, police holding a live breifing for reporters.

We're learning about cops' concerns that the woman driver of that Toyota Scion was so erratic that she might have been under the influence of something.

The car has been towed from the scene of the end of the pursuit that you see here near Rancho Santa Margarita. BTW, she drove 40 miles at speeds upwards of 100 mph. A miracle no one was hurt or killed but, California Highway Patrol says a lot of people were put in danger by this woman and they fully expect her to be charged with various crimes.

Cops did say at the reporting briefing that they were shocked when the driver started driving in circles at intersections and across freeway lanes. They hadn't seen anything quite like it.
