Back around 1994, my wife t-boned a guy who did just that (made a left turn right in front of her - SHE had the right-of-way). He got a ticket. She had a major bruise across her chest, was in pain for weeks, needed help getting up when she laid down, and totalled her less than 2 year old car - THEN HIS insurance company had the audacity to offer us about 1/3 of what her car was truly worth. I tried to discuss it with them over the phone - they hung up on me repeatedly. I went to speak to them in person - they threatened to call the police on me when I raised the BS flag to their "comparable vehicle" which was 4 years older, a whole different syle and had more than 100k miles than my wifes car. Things got really ugly with them for a while.

Having a recording a their drivers actions to potentially take to court could have been enough to get them to change their tune pretty danged quick.
