To operate the 1966 back-up camera...
1-Place foot firmly on brake
2-shift to reverse
3-place the palm of right hand behind passenger seat, or passenger seat headrest
4-look in all directions, left, right and in all mirrors for obstacles.
5- using your right arm for leverage, twist your shoulders to the right and pivot your head to look behind you
6-with continued attention to potential obstacles, slowly lift your foot from the brake and slowly proceed in reverse
LOL...I remember it well from Dad, from Driver’s Ed, and from my DMV Exam!
