But again, how brain dead do you have to be to see a giant parade of people and think “I know, I’m going to try to drive right through that!”

I'm not defending the person in video, she's clearly a clown herself. I'm just pointing out that these events aren't exactly helpful to the cause they're trying to advance.

How do I know? Because there’s thousands of people here. It has to be published somewhere if all these people are finding the route.

That's like playing go fish. Again there's no central organization to these events by design, so it's very difficult to actually track down where the information is. It could be on Facebook or Discord or Instagram or anywhere really. Good luck finding the right groups with the right info.

You’re not trapped in your car. You can back up, do a u-turn, and go somewhere else.

This easier said than done. If you're a normal driver, then you'll be stuck as they arrive. If there's a car behind you and the cyclists are already swarming around your car then you can't move else you'll risk hitting them.

If you are so stupid that you can’t realize you shouldn’t drive into such a crowd, you need to have your license suspended, as you are simply too stupid to drive.

Sure, but that doesn't justify these cyclists creating the dangerous situation in the first place.
