Classic propaganda device: if you're against calling X "Y", you must be in favor of X.

"Traffic violence" is not a thing. Call them "traffic accidents" as we always have, and we can move on.

And then, of course, bicyclists often run into other bicyclists, or into pedestrians. So now there's "bicycle violence"?

Soccer players often get injured, or get into fights. So there's "soccer violence"?

How about workplace accidents? They are also not inevitable and should be reduced. Are they "workplace violence"? Clearly not, that already means something else.

That is why it is accurate to call "traffic violence" a propaganda device.
