OK, guys, thanks for your suggestions, I have looked into it. I explained my situation to the fellows up at Car Toys.
First, they recommended that I just turn in my drivers license .......
I told them to get serious .......
Then they tried to sell me a regular back up camera ....... but, that wouldn't work, even with a BIG screen, because of my poor eyesight.
Then they mentioned a back up audible alert system, so I had to explain that I was hard of hearing.
One of the younger guys said that he could modify a autonomous emergency braking system with the sensors pointing out the rear of the car ........
BINGO! that's what I need!
However, my car is too old to accept that kind of modification plus the cost was prohibitive .......
After that, they escorted me out to my car and guided me out of their parking lot.
So, I'm back to driving in "semi tractor trailer style" ....... just try to avoid situations where I have to back up .......
