Or you could have a Troleybus: https://ku.wikipedia.org/wiki/Troleybus https://ku.wikipedia.org/wiki/Troleybus Does not need any rails and can navigate much steeper gradients & does not produce any local exhaust emissions. They together with trams form the backbone of publich transport here in Brno, Czech Republic. Some city quarters are on top of a very steep gradient that buses have an issue to climb yet troley buses don't have a problem due to not really having to lug around a power source, just the powerful electric motor. Most of the new troley buses now also have small bateries, which make it possible to navigate short stretches (couple km) where there are no troleys. This is super useful for both temporary redirections (where a street hosting a troleybus is being recontructed, it can go around without building new troleys) as well as for branching out to multiple destinations from the regular terminus when necessary. The couple kilometers of range are really not a problem as the troleybus changes when traveling under a regular troley wire and thus does not need any dedicated charging stations or charging stops. I really do wonder why more cities, especially in the west don't use more troley buses. My only theory being that they are somehow seen as outdated and not even considered when building new instrastructure.
