I personally think Battery buses with SAE J3105 'docking' points at key stops (basically, the stops that are used to loiter to set timing, rather than leaving as soon as possible) is a better solution than the cost of stringing OHL through every major road in a city.

Reading about this and matching it up with what I see in some more recent electric truck and ferry charging videos I feel this is almost historic tech.
