'Maybe I'm not surviving today': Man hurls rock at car on Seattle highway

A car dashcam video caught a man hurling a rock through a car’s windscreen as it was driven at speed along a Seattle highway, according to a report.

The thrower stepped towards the vehicle as it was driven on Interstate 5 late Saturday, according to the news website King 5. The rock left shards of glass showering onto the driver.

"It is a very scary moment. It's very disturbing. It's mentally very disturbing – maybe I'm not surviving today,” the driver, who gave his name as Soni, told K5.

"It is going to kill someone. It's going to cause a chain reaction. My two kids depend on me. So, it's going to destroy three lives in just seconds.”

Police told K5 nobody had been arrested.
