Unfortunately this is a sad situation.Just like when you have a stop sign at an intersection and the street you are turning into doesn't have a stop sign,the drivers without the stop sign have the right of way so they trust that you will not be entering the street until it's clear.
Obviously if they are driving recklessly and too fast they cause the accident but from the eyes of the police,they put you at fault,when you back up you have to check for pedestrians and any car movement.
make sure the cars blocking your visibility had not been parked illegally,that can be a decisive factor to avoid any claims just in case you go to court.
When visibility is low and when you are in a school zone.
As slowly as is needed to be safe.
This is not a question
You should always move very slowly while operating in conditions of low visibility. This is because you cannot avoid accidents if you are moving to fast.
Stuff is backing it up and stuff is flowing slower
Backing up while driving is putting your car in reverse with your foot on the brake and slowly letting your foot off the brake. If you are pulling out of a parking spot you might turn the wheel.
First get out and look, start the engine, put your foot on the brake, shift into reverse, look over your shoulder, release the brake, back slowly, watch your front end while backing.
If it is a standard transmission, you would need to slowly let out the clutch while backing up.

The famous buffalo of Yellowstone National Park moved slowly across the plains chewing grass, blocking the roads.

You need to practice backing up slowly in a deserted place with a curb that is out of the way of other moving vehicles, perhaps the outer limits of a mall parking lot. Repeated practice will give you a sense of when your car is near the curb.
