micromobility - Ebikes, scooters, longboards: Whatever floats your goat, this is micromobility
Ebikes, bicycles, scooters, skateboards, longboards, eboards, motorcycles, skates, unicycles: Whatever floats your goat, this is all things micromobility!
"Transportation using lightweight vehicles such as bicycles or scooters, especially electric ones that may be borrowed as part of a self-service rental program in which people rent vehicles for short-term use within a town or city.
micromobility is seen as a potential solution to moving people more efficiently around cities"

It's a little sad that we need to actually say this, but:
Don't be an asshole or you will be permanently banned.
Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.
Focus on discussing the idea, not attacking the person.

You also have good points. As it happens, near my metro area is a park which does indeed have a children's railroad that both crosses and then parallels a major bike trail. And it's absolutely adorable.
The point re: rubber rolling resistance and pollution is well taken. But I don't think the air resistance is negligible here. I realized now that the linked article doesn't describe the speed of this monorail, so I had assumed it was something like a sauntering 30 kph (18 mph), which if available 24/7/365 from rural areas into the urban core and had consistent on-time performance, that'd be excellent.
But this other article lists the speed for these pods as 60 kph (37 mph). That's kinda terrifying for a pod, where just the gyro components weigh 650 kg (1433 lbs), and definitely implicates air resistance. At that speed, the gyro had better be robust enough to counter sudden winds that would threaten to tilt one pod into the path of an oncoming pod.
Now that I think of it some more, on a horizontal curve, roads will widen the lanes so that vehicles won't side-swipe each other. And tracks are set farther apart than on straightaways, for the same reason. But the pair of rails? They're always 1435 mm (4 ft 8.5 in) apart, so will the pods be designed for a maximum curve speed and angle, or will passing be disallowed on curves?
Finally, I will concede that requiring two way pod lanes would definitely be a success story. But seeing as they're planning to use abandoned trackage, even a single-track railroad will already provide two "lanes" for their pods for free. If they had right-of-way that doesn't have existing track, it's not clear if their plan is to install a single rail.
I would say 30kph would be plenty especially for nonstop on-demand service. 60kph sounds unrealistic.
The reason I think you could lay new track is that kiddie train track is really cheap and used railroad rail is pretty valuable.
It would be simple to make self driving golf carts that followed a magnetic or inductive guideway or even used a virtually guideway with gps. There are a few of these available off the shelf right now. One I remember is dutch and there was another produced in Great Britain.
Railroad track is certainly valuable, although its removal and rehabilitating the rail bed can add up. Here in the USA, a number of disused railroads are simply left in place, usually only removing the points which connect to the mainline. I'm informed that part of the reason is due to regulations that make it hard to re-establish a rail segment if the rails are fully dismantled. I also have to imagine that if the rails are too valuable, unscrupulous scrap dealers would have made off with them already.
I certainly agree that any track used in service of a self-balancing pod has better of good or excellent quality, since we absolutely do not want pods coming off due to a rail issue.
I do like that all these ideas are essentially recreating the lazy river experience, but with no inflatable donuts lol
