I think OP is just pointing out that bike lanes aren’t the source of all traffic, as the recently passed Bill 212 tries to say. Even without any bike infrastructure, the Gardner is jam packed, and it’s not even rush hour.

Traffic is worsened by people driving cars badly, but traffic is caused simply by people driving cars. Cars are highly space inefficient, especially when on average they’re moving ~1.4 people.

Yeah, I feel like someone should make bumper stickers that say something like, “If it was safe, I’d be on my bike instead, and out of your way.”
