My wife was driving the car in was turning left on to a major road, she apparently hit another car trying to turn right on to the major road from opposite side. Both cars must have started from a stop sign and neither of them knew the speed. My wife does not remember the details of the incident, she was shaken up, initially declined to seek medical care but soon after could not recognize people, so had to be taken to ER. The car with all the technology failed to alert the impending crash, did not apply emergency brakes, nor did not record the event which it was supposed to have.
