I once saw a rear window get busted out on a CM ride. And another time, I witnessed a hit and run (angry, aggressive driver). The case made it to Judge Judy because somebody'd videotaped the incident. On the tape, you can hear me trying to calm the lady ("calm down, you're going to hurt somebody") but apparently our attempts at diffusing the situation got interpreted by JJ as heckling the lady. Still, she sided with the cyclist.
What happened on this ride? There's a reason I only ride in CM for the first 20 mins or so.
