In europe, voting typically happens in one day, where everyone physically goes to their designated voting place and puts papers in a transparent box. You can stay there and wait for the count at the end of the day if you want to. Tom Scott has a very good video about why we don't want electronic/mail voting: https://www.youtube.com/watch?v=w3_0x6oaDmI

If India can have voters vote and tally all the votes in one day, then so can everyone else. It’s the best way to avoid fraud and people going with whoever is ahead. I am sympathetic with emergency protocols for deadly pandemics, but for all else, in-person on a given day.

Washington State having full vote-by-mail (there is technically a layer of in-person voting as a fallback for those who need it for accessibility reasons or who missed the registration deadline) has spoiled me rotten, I couldn't imagine having to go back to synchronous on-site voting on a single day like I did in Illinois. Awful. Being able to fill my ballot at my leisure, at home, where I can have all the research material open, and drive it to a ballot drop box whenever is convenient in a 2-3 week window before 20:00 on election night, is a game-changer for democracy. Of course this also means that people who serve to benefit from disenfranchising voters and making it more difficult to vote, absolutely hate our system and continually attack it for one reason or another.
