我的几点看法

1 对方也说谎，对方说“ was attempting to make a left turn into the parking lot of Econo Lube and Tune when she was stuck by Vehicle 2“。从警察报告上的示意图可看出是Driver 1 struck Driver 2 ( driver 1's front struck driver 2's left side)，otherwise it would be "2's front struck 1's right side. It means driver 1 had
no intend to stop at that moment.

2 对方有没有绿色左转箭头灯很关键。

3 解释为什么老婆的车已经开到中间了还没有转弯的迹象，你可说老婆开车转弯比较大，看到 driver 1 不停冲过来，反映都来不及。也要解释你老婆为什么没开转弯灯，因为是车道有右拐的箭头。

4 不同意你太太执意要改证词。
