Thank you for your reply !

1. The traffic is just fluent at everywhere else. So this should be some sort of malfunction happening only on here.

2. The above is the result after I adjusted it...

>The method you suggested didn't work with the current traffic AI.
I see. I respect your efforts.
But I'd like to tell you again that stopping until the player hit (iii-2) is really unrealistic, and disabling it would be very appreciate.
Actually I had to quit some sessions because I got in the above situation on one way two-lane roads, and I couldn't move my car in any directions. Which means it sometimes spoils the experience.
You concerned that "It was just too easy to avoid", but the point of the emergency events is to train you to react to sudden movements, and it is not necessary to make it hit all the time.
What you are to simulate is not crazy guys who tries to deliberately hit you.

Thank you. We will think how to improve it.
