Guided bus
If the buses use electric traction and charge continuously whilst on the guideway, that could be a win, in allowing for smaller batteries and less downtime than a regular electric bus (especially if the unguided portion of the route is a “last mile”, comprising a relatively small proportion of the route). If they’re just regular diesel buses, it seems somewhat pointless.
Yeah, but what’s the advantage of it being guided? Instead it could have just be a private road that supports trolleybuses as well as emergency vehicles. Instead, it’s a gadgetbaun.
If it is travelling on a precise guideway (more precisely aligned than a traffic lane), then it is possible to transfer electrical power to it safely, either by aligning a pantograph with an overhead catenary or by a system of conductive rails, Once you can do that, the vehicle’s weight drops (as it doesn’t need to carry as much fuel), increasing carrying capacity and/or reducing the frequency of required road maintenance, Additionally, as electrical power is fungible (and can be sourced from whatever generation method is most economical), running costs are decreased over combustible fuel (as long as you don’t need to store it in the vehicle).
Is oftentimes better than a master of one.
People always miss that bit out.
Likely due to the phrase being added to over time.

Another version is: “Jack of all trades, master of none, but better still than a master of one.”
A number of old phrases have been added to over time.
