Amazing.
I'm not a business guy and I know nothing about commercial vehicles. But I have to imagine this setup is the hardest possible way to get into that market. I can appreciate wanting to build some kind of super-bus from the ground up, but unless your dream team is made up of industry veterans, that's not likely to work.
IMO, it would be better to start with ready-made vehicles and focus on attacking the underbelly of the establishment. Like bus routes that are expensive to service via conventional means, or communities that can't afford existing options. Or at least work with established players and solve their problems like logistics, labor, or cost optimization. Then you iterate and innovate from there, culminating at a "bus of your dreams" or whatever it was on the CEO's bucket list.
Looking at an industry that is over 100 years old and saying "we can do this better" from almost nothing is kind of insane.
Your telemetry and route visualization system sounds nice though - that kind of thing is in my wheelhouse.
