Crazy Taxi (and Simpsons: Road Rage") were largely about driving poorly, crashing into things, and performing automobile jumps that would be considered suicidal if done for real. It was a fantasy driving game with the taxi business as the thinnest excuse to be driving. Unless I've drastically mistaken what Rideshare Simulator is, I don't think Crazy Taxi example is applicable.
Fifteen years before Crazy Taxi, we had Space Taxi for the Commodore 64:
I'd say Space Taxi and Crazy Taxi had equal amounts of relevance to the taxi industry in the sense that they were an excuse to fly/drive in fantasy settings instead of an actual business simulator.
When I was forming my original question, I did consider an audience this might appeal to for those that couldn't drive (for whatever reason). I appreciate you sharing your POV on this.
I always considered Rideshare driving as the opposite of relaxing because of the physical dangers to drivers as well as the stress the drivers have from trying to make their money against rising fuel costs, insurance costs, and competion from platforms forcing down fare rates. Perhaps the Rideshare game masks all of these elements of the actual rideshare business and simply presents it as a task/goal game with a social aspect which would be far more appealing.
