This heart-stopping video has gone viral, showing a man nearly swerving into oncoming traffic on a Los Angeles street.
The man who recorded the footage, Anthony Braithwaite, said he knew he had to do something when he witnessed the erratic driving. "I couldn't let him keep going and hurt himself or hurt anybody else and you know it just had to be done," Braithwaite said.
Incredibly, he was able to get the driver off of the road! He probably saved countless lives.
