1. Larger vehicles pose a much greater threat to pedestrians and cyclists, both from frequency and consequence of incidents.
2. Tire emissions are more toxic than exhaust [1] and tire wear is dramatically greater on heavier vehicles. This is about air pollution in the city, not climate change globally.

Is there any info on how this impacts the environmental benefits of EVs? Or is the lack of combustion still a net gain?
Trying to summarize: EVs still seem to be a net gain, but non-exhaust emissions are still a significant problem. We don't know how bad that problem really is because there's not enough research yet.
Yes, out of the city ideally, you will use cargo train. In fact, in some (french) city lorry are forbidden, only local service are permitted. The most heavy one are already forbidden on the WE, day off and summer all over France.
But then you'd need to have a viable alternative and that's a bit of a problem for 'last miles' delivery of goods. But in-city SUV traffic is entirely optional.
Passwords need to be sent both with the request, and to the requestor. I think GP is referring to sending credentials to the service making the request.
It is far better to give service XYZ a time-bound and scope limited token to perform a request than a user's username and password.
Few people have screens as high resolution as even a mediocre phone camera.
Before someone brings up future screen tech, there are additional reasons that's not a trivial workaround. Additionally there's a higher benefit to having high resolution cameras which have a wide field of view and the user may want to zoom in on the physical data vs a screen where the zooming happens in software.
Only 19% of electricity generated today in the US is from coal, trending toward 0. Then consider larger fossil fuel power plants are far more efficient than the tiny engines in vehicles.
"Coal is used to power electric vehicles," is an argument that is more noise than signal.
This is regional dependent. The last time I looked in Colorado, and electric vehicle is actually spews more pollution when running than a gas car b/c of the amount of coal power plants that we run - much to the chagrine of all the Boulderites in their Teslas.
Colorado is 30% NG and 30% coal, probably because a lot of coal is mined in adjacent Wyoming and MT. The rest are renewables. The coal number keeps dropping, so EV use will improve over time without upgrading the vehicle.
