@EUCommission It's a neat starting point, but I think we can do better.
First, accessibility. From the screenshots these look very cramped; I certainly doubt a wheelchair user can use this, to say the obvious. They're going to need to be bigger.
If they're going to be bigger, then let's accept that and see what we can do. If environmentalism is a factor here, then it probably makes sense to make these bike-accessible; people will still need to go places to and from the monocab, after all, and there's no cleaner transport than a bicycle. Give them some free space where occupants can store bikes, or maybe large bags and cases.
And then, capacity. Look, on-demand access for a couple of a people at a time sounds nice, but in practice lots of people are usually travelling on similar routes at similar times, and it's far more efficient (and so environmentally friendly) to allow lots of people to travel at once. Plus, that will enable families and friend groups to travel together easily. If scheduled stops are regular enough that no-one needs to travel far to get to them, you get the best of both worlds; comfortable, clean travel, catering for large numbers of people, available at a stop near you. So given we're making this bigger anyway, let's scale up significantly; we can get multiple dozens of people in a cabin with the footprint of a couple of cars.
With that amount of size, we can probably spare space for a few amenities; maybe every second monocab can have a small toilet around the area for bikes and bags, or every third can have a small staffed area to buy drinks and snacks, offset the costs a little bit. It all improves accessibility and overall quality.
Although, now I think about it; now it's a lot bigger, it may be a bit more difficult to reliably stabilise with a gyroscope. And besides, a gyro adds a good amount of weight and complexity. If we just add a second rail alongside the first one, the vehicles won't need any fancy tech to stay upright; at most, perhaps some suspension to handle turns, depending on how tight they are and how fast it goes. That'll let us get even more usable space, as well.
...Hang on, did we just invent trains and trams again?
