So what you are saying is that in EVERY single case, the drivers would have to be doing the EXACT same thing EVERY SINGLE time.

That is a great way to solve a problem in a controlled environment, but it doesn't work that way in the real world. People are not robots and they don't all behave the same way every time. They have different strengths, personalities and driving habits.
To attempt to make some sort of assertion that every one of these people had to do the exact same thing as every other one is ludicrous.

Are they all lying or do they really not know and are trying to remember as best they can? Are they making assumptions? Well I always do this, therefore thats what happened that day... When in reality they may have done something different and do not know or realize it.
