Clavicle Error - Broken Collarbone

I was knocked off my bike earlier this evening by a bloke on a mountain bike who unexpectedly and stupidly pulled out in front of me without looking at all. Full high speed impact with him and then the road. Ouch.

Consequently I have a broken collarbone. How long should it take to heal?

I got the guy's number - are there any other details I should have taken?

Ta.

I broke mine last year. 4-6 weeks they said but I was riding after 3. It hurt a bit tossing a messenger bag over that side the first few months because they dont heal very flat.
