>>All other evidence can be argued in a court of law “if” the officer writes a ticket.
I assume that you want your car fixed. Most traffic accidents don’t even get a ticket unless injuries or aggressive driving are present. But, the insurance company will insist on a statement and they will assign percentages of blame to determine how much of your damages they will pay for.
It is best to talk with an attorney before making any statements to police or insurance companies. Your silence is not an admittion of guilt, but to:
..." tell the cop that you saw him coming over and held your ground because he had no business entering your lane."
is.
