I tried to find the source of this and all I can find is "webpronews" which says:

With $75 million in annual revenue, 28,000 daily passengers, and 150 Teslas in operation, this underground transportation network is redefining how cities think about mobility.

So if it's 28000 x 365, that's $7.50 per trip. Of 1.7 miles. That's suspiciously double the $3.75 listed on the Vegas loop site, which also offers a day pass for $5.00.

Still, even $37.5 to $50 million is some pretty significant revenue (not to be confused with profit). Does it carry 28,000 riders per day though? As best as I can tell, this is what a publication from the Board of Directors of the Las Vegas Convention and Visitors Authority claims is the record ridership, set during a Specialty Equipment Manufacturers Association convention. Even ignoring the suspiciously round number, the publication notes that rides were free on that day, and obviously it's blatantly wrong to apply a record total to a daily average.

So essentially, the tweet is a dishonest interpretation based on another dishonest interpretation of dubious statistics. Lesson is, everything on Twitter is bullshit - emphasis on every. Even subparts of bullshit on Twitter are still bullshit, often layered on other bullshit. Twitter is the last asshole of the human centipede of bullshit.
