Another great safety idea to prevent lane change accidents would be for the Volt to have rear turn indicators (or turn signals in American) instead of the flashing brake lights seen on most GM cars.
Perhaps. But the number of times I've had to make evasive maneuvers or stand on the brakes to avoid an accident is unacceptably high. It could also be that I learned to drive in a country that required amber indicators, hence the red just does not register in my brain. This is particularly true when (most) people initiate the lane change at the same moment as they turn the indicator on.The reason America has never gone to the amber turn indicator is that it has never been shown to actually reduce the number accidents and it adds additional cost to the car.
