The cynical take is that EV's don't exist to save the world, they exist to save the car industry.
The more neutral take is that between an EV and an ICE car, the former is preferable.
Fact of the matter is that in order for many people to use a private car to go from anywhere to anywhere, you need a shocking amount of space and resources to make that work, especially if you compare that to expecting most people take those journeys by mass means, by bicycle or by foot.
So if you propose electric cars as the silver bullet solution for climate change, in a place where walking, cycling and transit are systemically kneecapped and held back, and nothing is done to solve the latter part, then the environmental impact of EV's is a drop on a hot plate.
I think pretty much anyone would agree that pervasive public transit with pervasive coverage and short wait times would be pretty much ideal.
I hate to be cynical but I can't see us getting there any time soon in the US. Mainstream American culture is so delusional about the idea that we're all RUGGED INDIVIDUALISTS that the idea of touching people is utterly repugnant.
I would love to dream of a world where this could happen, and maybe I should stop dreaming about self driving cars and start dreaming about this instead :)
Meanwhile, public transit everywhere in the US besides Manhattan is utterly abysmal and even in cities like Boston where public transit is decent-ish most people who can drive do.
Those who can't either take a taxi/Lyft if they can afford it, and if they can't afford it they suffer. It's the American Way.
One issue is not simply attitudinal (I have the right!), but habit/expectation (this is normal!).
A lot of people already structure their lives around cars. It's hard to get someone to go from "yes, it is normal and right for me to travel 40+ miles a day for errands" to "it is unreasonable for someone to visit these 5 places across town in a single afternoon".
Meanwhile, let's also face that EV's have to carry around large batteries. One advantage that ICE cars do have is the power density [J/kg] of petroleum fuel is leaps and bounds better than that if a lithium battery. This means that EV's are likely to produce more road noise from rolling, the dominant source of noise above 50 km/h, as well as more wear to the roads, since wear is a function of vehicle mass to some pretty high power. (I thought it was m^(4), but I'm not sure)
On top of that, while EV's don't have any tailpipe emissions, the power that they need still needs to come from somewhere. Thus the carbon emissions for use are a function of the national power grid of the place where you're charging your car.
Thus, A) if cars are already a fairly small part of the transportation mix, B) steps are taken to further improve the quality and availability of alternatives to cars, and C) the power grid is dominated by nuclear power and/or renewables, then EV's could be better for the environment.
