What do you think?

Let's say an accident occured in an apartment complex. Driver A was going through the neighborhood at normal speed. Backup lights of another car go on when Driver A is approaching behind the car. As soon as the lights go on, Driver B backs up (leading to the fact that they never looked behind them or else they would have seen the approaching car) and hits Driver A on the passenger rear of the car.

Isn't Driver B at fault?
