I wasn’t talking about people on group rides, I’m talking about people using bikes as a means of transportation. I agree that people in group rides can sometimes be bothersome road users.

Red lights and stop signs are designed for cars and it’s honestly stupid to expect cyclists to treat them the same way. Studies have shown that treating stops as yields when on a bike is safer for all road users.

You should know that it doesn’t take “motor vehicle speeds” to cause a (serious) accident.

That’s not what I said. I was pointing out how your “swerve into a post because a cyclist ran a red light” is a dangerous situation made possible only by the presence of cars.
