The accident was caused by a mechanical issue (my brake levers not adjusted properly) when lane-splitting behind him on 101. He had done some sudden braking and I wasn't able to fully stop in time.
I broke his taillight, he was a gentleman about it and just asked me to cover the expense of replacing it.
When we were on the shoulder exchanging info, CHP stopped by and queried him about the rollerblades, he does have a handicapped plate and a court order allowing him to ride with them on. He had previously broken his pelvis and can't walk around easily, and said that he can't drive or take public transit. CHP was incredulous but let him go with his paperwork.
Oh, after I hit him, I fell over. I mostly lifted the bike back up on my own, and someone hopped out of their car and helped with the rest, then I got over to the shoulder. Later on, when I was talking with him about the taillight, he apologized and said he should have helped me lift my bike. I have no idea how he would do so....
