Deputies from the Santa Clara County Sheriff's Office arrived at the coffee shop Thursday afternoon to respond to the collision.
An image tweeted by the Sheriff's Office shows a dark blue BMW halfway inside the coffee shop, surrounded by glass shards and some overturned furniture. A second image shows the car entirely inside the establishment.
The two bystanders, who were inside the Starbucks, were taken to a hospital.
The driver was unharmed and is currently cooperating with authorities.
This investigation is ongoing.
