some motorcyclists have been out in the sun too long

During the past six years, deaths of cyclists have risen in Florida. This is an expected result of repealing the law requiring helmets. Here's the story, although the writer demonstrates the kind of sloppiness in dealing with statistics that we've learned to expect from the news media:

I love the attempt by the helmet law opponent to change the subject by saying: "What causes most of the crashes is cars," he said. "Usually, it's the car driver turning left at an intersection and causing an accident because they didn't see us coming."

Sure, and removing your helmet is going to make them see you better.
