Had something like this happen to me, some old matey pulled out while I was driving along (he pulled out from a junction onto a main road and basicly didnt accelerate quick enough!!) and i had to swerve around him, damaged my front left wing and scraped the back corner of his. He tried to blame me as i was young and went into the back of him when he full well knew that he pulled out without looking, especially as he could have waited 2 seconds and slotted in behind me as no other cars were behind me!
Basicly dont let the old guy try to blame you as your young stick to your story and try and get a 50:50 out of it or for it to be settled out of insurance.
