Lead Balloons (2021)

Set in a dystopian reality we follow Abe, a lonesome perpetual coward who decides to end his life with the help of a suicide service: a mysterious, self-driving death cab. During this gritty ride Abe passes several characters - all representing the absence of hope through a different looking glass - reminding him of his own wrong turns in life as he drives towards his final destination.
