313 people were killed on local roads in the DC region in 2022. And 0 people were killed in the incident referred to in the post.

The fact this your comment is upvoted 7 times (probably because no one recognizes that it's off by an order of magnitude) in response to my -34 comment is proof that people, and probably r/washingtondc redditors in particular, have an extremely inaccurate understanding of the relative risks of driving vs. the metro.
