If you were to pick two racing games further apart on the spectrum, it'd be hard to find a wider gap than "Mario Kart 64" and the early-access driving sim "Assetto Corsa". The very idea of adding realistic physics to one of the most tantrum inducing tracks of the series is something only a derelict or perverse mind would think of... which brings us to N64AC, who built, stretched, and tweaked Rainbow Road into something that was even possible to drive on.
This video by megaspeed2v2 showcases how an actual attempt to powerslide and swerve to the finish line would look a lot like my road test in 11th grade, but with less swearing.
