This may have something to do with which states do all-mail voting:
Eight states—California, Colorado, Hawaii, Nevada, Oregon, Utah, Vermont and Washington and the District of Columbia—allow all elections to be conducted entirely by mail.
Utah is deep red, but the others are quite blue. Especially with California in there, that's a pretty good chunk of the US that votes early by default (there are same-day options in these states, but I suspect that option is often utilized due to procrastination rather than intentionally waiting until election day to vote).
Hence why the members of c/fuckcars are so intense (I include myself in this).
The only practical way to avoid exposure to society's car dominance in your everyday life is to live far from society... Which ironically forces you to own a car and drive to get literally anywhere.
