A couple of us engineering students were working on installing a car stereo in our friend's car. While under the dashboard, I felt obligated to open the fuse box and jumper his blinker to the interior light and his horn to his brake light.
We watched him drive off...when he hit the brake the car slowed and the horn blared. Problem was that it startled him and he took his foot off the brake and drove into a bush. Luckily, no damage was done and we happily fixed his braking problem. When I got in the car with him six months later, his interior light still flashed with his turn signal!
This is an very good example of our minds fixing into regular activities. It is never a horn sounds when brakes are applied.So when this happened he could not steer the vehicle properly. The mind is as big as space and it is so powerfull.
