If the green car is at another 2-3 cars lengths back it would not appear on the right side mirror, only on rear view mirror and it is safe to change to right lane, assume that the green car is at same speed, this means you should monitor mirrors constantly every few seconds, especially just before you want to change lane.
As shown in the CarandDriver illustrate, the green car is too close for the blue car to change lane, safe lane change is when you have 4-5 car lengths opening if the car on the lane you like to change to is at the same speed as yours.
Many drivers don't know that rear view mirror is for seeing cars in the rear, side view mirrors for seeing cars on the side lanes, side view mirrors are not for seeing the rear panels of your car.
