In my idea world these would be in the rural areas that public transportation couldn't serve and they'd carpool.

Someone shared a fan made mod to add one of these to Assetto Corsa in a thread I made a few weeks ago about sim racing. I've been working on a personal best lap in one of these around Laguna Seca, and it's probably one of the most fun cars I've driven in the game. Putting 20 of these on a track just turns it into very aggressive traffic and it's so much fun.
