I had a much longer comment here but I ended up scrapping it since it would make for too long of a discussion. I'll just quickly address a few specific things:

> added right before the election

I feel like it's not hard to counter-argue that the writing has been on the wall for decades and it's not a genuine surprise at this point.

> So the actual argument is not that there is link between race and going to dmv once in 10 years

IMO, it's probably better to make the the actual argument.

> DMV
