I object to that, since it compares packet loss to a catastrophic
failure. (I would personally argue against a car analogy in the first

I'm not sure what kind of buffer you're trying to illustrate. That's
certainly not how I understand tail-drop buffers.
Finally, I'd argue that you're being too harsh on QoS techniques.
