What I'm reading is that this isn't a formally organized event, and taking up the whole road (when it isn't blocked for that many riders) would not be legal there.

This driver is am idiot, but so is the club for not formally organizing and working with the city.

Am cyclist, want people to be smart and safe.

Based on other comments in here, this isn’t an organized event. It’s just a group of bikers that do this every single weekend.

Yes I don't know if this is a governmental issue or an issue with the event organizers.

Like obviously don't drive in the median and break traffic laws, but this kind of event not being appropriately managed is going to increase the likelihood of accidents. Mostly from assholes driving poorly
