It's like FaceMash, but with photos of F1 cars
In RaceMash, you're presented with two randomly picked photographs of F1 cars from the 2022 season. Below them you'll find buttons for placing a vote for one of the images and an extra one for declaring a draw. Once you've placed your vote, another pair of images gets picked and the cycle continues.
Every vote you submit gradually fills up a progress bar and if you reach 25%, 50%, or 75%, you'll be awarded a fun fact about Formula One. Once you've submitted all votes, you unlock a ranking page that reveals the photos' final ratings, where the images are ordered by said ratings descendingly.
But how are these ratings calculated? Each photograph has a base rating of 1500 points (as well as a few other parameters you don't need to worry about) that gets updated using the Glicko-2 system every 12 votes you cast.
