I agree that more bike lanes are needed and also cyclists need to be treated with the respect any life demands.

But flipping off a driver or generally blaming people who drive is fighting the wrong fight. I drive a car, I also cycle, being in a car doesn't make me anti-bike.

Fight the government - flip off the government - that is refusing to put in safe infrastructure for the bikes (with protests like this, of course. But don't flip off the driver, at best it does nothing, at worst it widens the gap between both groups and makes it easier to dehumanize and villianize the cyclists).

This looks like Miami. If it is.. critical mass usually has a police force in the loop they do usually to stop people driving right through the crowd. The loop is posted online about a week before and there is always police presence

bicyclists are taking up all of the street

It’s not legal

It is absolutely legal. The driver's manual for my state:

Bicycles are considered vehicles when on roadways. Bicyclists are required and expected to follow the same rules of the road as motorized vehicles. As a motorist, you should know that a bicyclist has the same rights, privileges, and responsibilities as you. Respect for each other will aid in the smooth flow of traffic.

Unless there's a bicycle lane, bicycles get the full lane of regular streets like any other vehicle. On highways, they stay close to the right boundary. Bicycles are passed with abundant clearance.

Edit: Full street? Nevermind.

For all of the unequivocally civic commenters on this thread, ask yourself this: would you be defending someone driving through a protest if the protesters weren't on bikes?

Protesting the lack of safety for riders by being unsafe riders? I don't think the best way to convince the public that cyclists can be safely integrated into traffic is to purposefully create dangerous situations.

I'm all for bike activism and fuck cars. But what they're doing is illegal and the driver likely had no idea what's happening. If they weren't riding the wrong way, then everything would have been perfectly legal (at least here in Germany). As long as the cyclists form a mass, they're considered one long vehicle and can even pass red lights that way, as long as the first person did so with a green light. But riding on the wrong side of the road and expecting everyone to know what is going on is kind of a dick move and just brings more hate on cyclists.

Meanwhile, in Germany: §1 StVO
