Hope all the best for your friend it can be hard commuting on a bike. Had the same thing happen to me about 4 months ago leaving work one night and got hit by a driver doing about 40 miles a hours and just take off left me pretty messed up broken neck with 5 bones and fusion surgery.but as hard as it was to heal back on the bike and still commute to work its a hard thing to give up riding.just pay alot more attention now and mounted some mirrors so I can monitor my rear a little bit now
