@pumpkin9916 First, you make it sound like the manufacture of a car is a trivial amount of the thing's lifetime GHG emissions. It's not. Estimates vary, but the lowest one I've seen still says that 20% of the car's emissions will be from its manufacture.
Second, you realize a Tesla still uses oil, right? That differential is not lubricated in electrons, and neither are wheel bearings or suspension points. Even Elon has to do business with Exxon. Yay, capitalism!
There are also the huge tires which have a high embodied energy cost, and wear fast with 5000 pounds and almost 500kW bearing down on them. Oh, and the Saudi Arabia of rubber (Indonesia) gets 87.5% of its power from "dino" and coal. (Source: https://www.geni.org/globalenergy/library/national_energy_grid/indonesia/index.shtml)
Oh, and let's not forget the power source used to charge the mighty (large) Tesla in many (most?) places in the US is also coal, nuclear or/and natgas. Every mile driven is more pollution for people not lucky enough to be inside the carbon-filtered cockpit.
Up here, Quebec has massive hydroelectric dams covering several thousand square miles, and makes enough power for its own needs and those of several states in the US Northeast. The trouble with that? The land flooded by damming was mostly forest, which actually makes more GHGs in decomposing than the entire project will save over the course of a century. No shit.
It also results in the leaching of lead into the water table, killing both the wildlife and Indigenous peoples (Cree, Inuit, Innu) who live in Northern Quebec with disproportionate levels of cancers and reproductive harms associated with (wait for it...) exposure to lead.
The key point here is, regardless of fuel source, hammering the shit out of your car pollutes a lot more than not doing so. A lighter vehicle will also out-accelerate and out-brake a heavier one -- all other things being equal -- while requiring less fuel do to so (again, regardless of fuel type).
HTH.

@Andytlp You're generally right, but it should be pointed out that any electrical system is most efficient with the shortest possible circuit, which doesn't favour huge generating stations located hundreds or even thousands of miles from the intended user.
There are also environmental costs to large-scale generation projects, that will last for centuries after the last electron has been wrung from them (e.g. the huge hydroelectric dams in Quebec and Labrador, where mercury is leaching into the water that people and animals drink, with devastating consequences).
Oh, and there's also the issue of storing this wonderful grid energy, which is no small matter given the exploitation of places with lithium deposits usable for batteries. Like, the name "GigaFactory" should clue people in that things being done on that scale cannot be considered benign from an environmental standpoint!
People need to consume less everything, regardless of the fuel source used. Teslas are good compared to dino-burners, but dog shit compared to ebikes, which themselves are dog shit compared to regular bikes, which are dog shit compared to walking.
So, in short, just walk there.
