BigBread's No Destination is a "game" in the classic spirit of Desert Bus, and you don't even have to make the occasional steering adjustment. Just sit and enjoy the journey, looking out of a train coach at the procedurally-generated hills and woods of wherever it is you are.
It's just the first entry I've checked out from from the 2019 ProcJam — "Make something that makes something" — and there are dozens more experiments, artworks and according-to-Hoyle games to enjoy.
An endless train ride, a sitting simulator.
Just a relaxing time
