Thanks all for the well wishes. Just to clarify I was hit from behind, clear open road, broad daylight, sun behind us so nothing to affect his view. Police mentioned at scene he said he was reaching down for a water bottle,he should have seen me well before so yes possible phone use. He is also local so would know that road very well. Police are calling me at the weekend.
Just checked bike, rear derailier knocked off, rear wheel buckled, It is a carbon frame and seems to have a crack on the underside of top tube, not skilled enough to know if structural or just the paint. I have his insurers details from the police, I’m sure I just have my bike on the contents cover, so not sure what I do now? Help appreciated.
