Drivers Education and driving tests are two ideas that come to mind.
Why did this get downvoted? I think it's a valid question -- obviously all of the current mechanisms in place fail to implement this, as can be observed on the roads every day.
I think a real test for drivers education would be a start. I took my test in Kansas and it involved turning left, turning right, changing a lane, and stopping at a stoplight. The entire test took less than 3 minutes.
At this point, I think most people would lean towards taking people out of the equation as much as possible.
