A motorcyclist in Philadelphia is in serious trouble after video caught him kicking in the back window of a car with two children inside. The mother got out to confront him, and he argued with her, at one point headbutting her in a disturbing escalation.
Violence directed at a family, with children present, is especially alarming. The arrest is a reminder of how dangerously out of control road rage has become, with confrontations escalating to outright assault.
