When a car drove into an Austin hospital, it left the driver dead and an entire family among the injured. Now that family is speaking out. One key question: why didn't the hospital have safety barriers in front of the ER entrance to prevent a car from driving through? Our team looks at similar crashes around the state and across the country, as well as at the barriers that experts say could prevent disaster in the future. Plus, we examine promises of policy changes from elected leaders after watching our report and seeing the lives impacted by this crash.
