I'd go MIB.
Now the inspection - if you're inexperienced then defo get it checked out. Save the invoice and also ask them to price for a full repair. This is so you can claim from the MIB. Take pictures of the damage. If you have pictures pre crash that may help.
The other thing is don't check the armour, check the leather isn't significantly thinned where it has slid and that the stitching hasn't been compromised.
As for why it happened... did you anticipate the potential for bad drivers coming the other way and did you take appropriate action? Unfortunately the DSA teach people to sit in the centre of the road. This is fine until you have passed your test.
Basically if there is or may be unseen oncoming traffic, make sure you're as far away as possible. For a blind right hand bend, keep left if it's safe and vice versa. If it's the blind crest of a hill, people will still cross that white line to pass a cyclist so keep left away from them.
This was clearly the fault of the car driver but have a good think about what you could have done to position yourself away from danger. If you've passed your test, get yourself a copy of motorcycle roadcraft. Some people poo poo advanced riding but by the sounds of it, it could well have saved you from someone else's idiocy.
I hate it when people drive off after sending you off. It happened to me. Best thing to do if it was during commuting hours is to put up a picture of you in helmet and leathers (big picture) and the bike (ideally one without crash damage). Couple this with some flowers and tie it to a nearby tree. That might well get the bastard to turn themselves in or at least cripple them with guilt.
