I will be it will be a 50-50 determination.
I was driving north on rt 23 (15 years ago) in the center lane with no cars in my lane for at least 1/4 mile, when a guy in the left turn lane changes lanes in front of me, and he admitted it to CPD, yet because the damage showed I was behind the vehicle ever so slightly, it was decreed that we were each responsible for our own vehicle's damage!
