Hopefully SMIDSY, "Sorry Mate I Did Not See You", applies rather than someone having a contract out on you. Since it has happened and you are OK I guess you get to fix what may have been there before or what happened as a result of it. I guess there may be a question about 'liability' if you made contact or otherwise.

Reminds me of the time, memory probably fails me since it was a long long time ago,

I was going home from College, also at a good pace, and someone decided to drive their car out of an underground car park in front of me. I almost stopped the bike but the handlebars got turned for me by the final impact with his front wing, or I may have flinched, and I ended up rolling over his hood landing on my feet on the other side. I go back and pick up the bike, tell him I am OK and pedal off. I cannot say for certain that I did not see it coming when it presented itself and reacted subliminally.
