Rather than wait for fatalities, I think I would discreetly alert the authorities and suggest to others that they do so, too.

It's been noted by some that cyclists are highly unusual in that so many of them wish laws were better enforced on their kind. Ya don't see too many truckers wishing... or doctors... (won't bring bankers into it)

Our fast group... yea, there's ugly ego inflating that happens there and a need to trash others. Most of them have quit our club, since the club prez was in said group and wanted to abolish membership and the newsletter (that I wrote) and ... "nothing personal" ... but abolish the board positions of (wait for it) all the people who weren't type A riders. Because we didn't need that stuff, we would figureo ut how to do it online or something, and the club was too involved in things that weren't riding. (Oh, and one of them firmly believed that commuting by bicycle was just wrong.) Not sure where things will go, especially since I've said I don't want to be president after this year because it really is time to bring in new blood...

but your guys are endangering themselves and others... thelaw may not care... maybe a 'name witheld' letter to the editor...
