I'm glad the accident wasn't worse, and I wish you a speedy recovery.

As far as being invisible while riding over 25 mph... I once had a driver look directly at me while I was descending a hill at 35 mph, and he then proceeded to pull out from the driveway, cut me off, forcing me off the road and over the handlebars. His explanation: he misjudged how fast I was going. It was an honest mistake on his part. I think that many motorists haven't ridden a bike since they got their drivers licenses, so they associate cyclists with the speeds they used to ride when they were 14 and tooling around the neighborhood. Wear bright clothes, keep your eyes open, and try to anticipate the "worst case scenario" when riding in traffic.

But more importantly, get well quickly. There will be plenty of opportunities for carnage in the upcoming racing season.
