Lucky there. Its amazing how difficult it must be to see bikes. Maybe we notice them more because they play a big part in our life. We are actively looking for them. This is not supposed to be an excuse for lack of observation.
Main thing is you are ok.
Hope you have more luck with insurance than I. Knocked off while stationary in Sept. First the other side tried to blame me, not the driver though, then they offered a 50:50. Still fighting it, whilst still limping. Don't give in!
