If we're fantasizing about eliminating some mode of transport, my vote is for cars. Most of my initial parent comment's concerns would go away if there weren't any cars, and pedestrians would be safer on crosswalks too.

In reality, though, we all have to get along. And those concerns are addressed by cyclists not riding at breakneck speed and going blindly around corners. I don't see either of those behaviors very often in my area.
