I never implied this. I stated that there was a misjudgment of the speed of the vehicles, not the space. No one was cut-off. She realized that the vehicles were going faster than she expected (faster than she could accelerate to match the speed of) after turning into her lane and seeing them closing in in her rear view mirror. If she had the time to observe this in her rear view mirror after making the turn, and re-act to it by maximizing her acceleration, then the other driver behind her had even more time, considering he also watched her make the u-turn. No one was cut-off.
