Classifying something as a textbook whataboutism is typically itself a rhetorical fallacy. It is rare for it to be used in the sense of identifying a real problem. Normally when it gets invoked someone has an argument, often a reasonable one, and someone else wants to pretend it isn't a valid but can't come up with a logical inconsistency.
In this case nxm's comment has formal problems - it is just irrelevant. True or not, it doesn't justify mowing down cyclists.
What was the comment trying to say?
the downvoted comment sounded like textbook whataboutism to me. those who responded have their antennae up for rhetorical fallacies.
