This is immaterial considering EV ramp rate and overall fleet turnover trajectory. Public transportation is also non existent in most of the US. Agree with your mass transit points where density and planning allows (bus lanes, fast busses, even free bus rides). Importantly, an EV rideshare fleet should be considered where using bus routes is inefficient to due low density. Congestion charges are also likely helpful where there is high density (Manhattan, Chicago Loop, parts of they Bay Area, Washington state, Philadelphia, Washington DC, etc).

TLDR: Mass transit, lower speed limits, and traffic calming in urban (and suburban, where reasonable) areas. Electrification for middle of nowhere.
