A MacIver (8-Bit) Perspective
No, Atari did not release a game about roundabouts in the 1980s. This is a “homebrew” game programmed by MacIver reporter Bill Osmulski. In this video he runs you through the levels while talking about some of the random roundabout facts he’s come across while investigating Wisconsin’s transportation funding. By the way, yes, the game can actually be played on a real Atari 2600 if you still have one.
