Interesting to read comments. Some, clearly, are taking advantage of the opportunity to promote their politics or business. Others are struggling with the need to be seen. On that subject the verdict has been in for quite some time.
Clothing and visibility standards for highway workers and other occupations recognize that roads are dangerous places. People who wear those vest and other clothing don't do it as a fashion statement. They don't argue about their right to be where they are. They do it because after lots of analysis we know it saves injury and death.
Cyclists also need to understand that the same rules of life apply. See and be Seen is the rule on the road and in the air. No academic discussion or political agenda or fashion argument changes that. We are different only in that there is no law or military commander making good sense decisions for us. We are responsible for our own survival.
