It sounds to me like you're doing everything possible to be safe. We're close to the same age and I too ride a lot with lights, helmet, bright clothes and situational awareness. But there is just no accounting for idiots. Glad you're doing better. I've only been hit once and not seriously. The person never stopped to even check on me. I was shaken and it took a while before I could mingle with traffic again. I stuck to mups and alleys for awhile as I couldn't stay off the bike even though I couldn't get back out in the mix of things. It came with gradual encounters and now I don't even think about it. That was about 3 years ago.
