i know these are remarkably stable, but i would still feel uncomfortable sitting on the top level..
Not only is the tram very narrow, but the wheels are so close to the centre, it looks like the tram could also fall forward or backward easily
the thing that's so unintuitive is that it's got so much weight at the bottom that it's probably more stable than many vehicles you never even consider as being able to tip over.
not only is the centre of balance actually quite low, but it's also so monstrously heavy that you'd need to ram another tram into it at speed to move it.
