In you case, the only disadvantage is that change lane story;
Are you sure that cop put this in his report;

This is the only point I was worry about; fight for it and learned your lession;
Be smarter;

Due to if unsafe change lane and cause the accident, your 100% at fault;
if pure tail in, his 100% at fault for sure;

Anyway, fight with them and contact with the insurance to address the situation (never mention that change lane story again)

if you lose the fight, lane change story will be the only reason drag you down;

I PM to you friend.
