General Motors Corp. unveiled new vehicle technology July 13 that will determine the severity of a crash within seconds and automatically call for help, according to an Associated Press report. Crash sensors in the front and rear bumpers and on both sides of the vehicle can tell where the vehicle was hit and the speed and force of impact. Beginning in some vehicles next year, the information will be sent to an OnStar operator through a hands-free cellular phone connection. The operator can talk to crash victims in the vehicle and conference in 911 dispatchers with all the information they need to quickly send emergency responders, according to AP.
