I've ridden on BYD electrc buses for about 8 years, and on hybrids for a few years before. I live in China, which has a lot of buses, and BYD have a lot of market share. To share some of my observations with your observations: Decoration signs/asthetics - Poor client requirement. It isn't hard to say how large a display should be and cut the shape. I found the design of the front windshield interesting. Very curved, looks oldskool. Cute. Traffic in Chinese cities is pretty start-stop, with buses kings of the road. No one will try to cut-off a bus. You're right there's a lot of torque. Drivers should not be switching type of bus more than once ever (per change in model). Lines replaced here are replaced overnight: all buses serving the route yesterday replaced with new buses today. The drivers do need time to get used to the new power supply, and also the new balance of weight bus bus now has (diesel and wheel-base applicable too). When passengers and driver have gotten used to it, the ride is very smooth. For charging: Peak time is rush hour. Buses going about 150km perhaps over 4ish hour time slots (urban). During the day they charge (relay team, one takes on lower frequency scheduling while the other charges, on destination another goes off-charge while the returning bus charges). When all on a full-charge and in evening rush-hour 3-4 hours everything is sweet. Charging and usage-patterns shouldn't be a problem for a bus.
