Its not big, not clever, never planned and mostly hurty. Not on the commute, but over 20 years MTB and road riding and many miles I've hit:
-a rambler while MTB'ing descent in Lake District, I only clipped them guv, them fine, me fine, but comedy over the bars and cartwheel into ferns. Everyone saw funny side, no harm done.
-a drunk while filtering in London - them fine, didn't even drop drink! Me over bars into back of parked van, whiplash and neck not pain free for next 9 weeks
-a druggy on phone in London -them fine, me sprained wrist and hyper extended tendons, wrist not right for 3 months
I've crashed into my mums dog in Wales too, does that count? Well he crashed into me really, just as I arrived home after a long ride, it shot out of the bushes (lurcher) chasing something, straight into my front wheel. causing a crash literally on my mums front door step. Both fine, I laughed later, but wasn't laughing at the time.
And I got hit in the face last week by a pigeon who was too preoccupied hassling another pigeon for some nooky, this is the second time this has happened to me, literally spitting feathers. Not even the Daily Mail care about cyclists hitting pigeons.
