Always important to remember in this debate: electrification of transport is not just about carbon and climate. It's about public health, not to mention public sanity.
The filthy noisy combustion engine was never compatible with dense cities, which is where most people live these days. Anyone who has been to one of the few places in the world where urban transport has been completely electrified will testify to the difference it makes to be free of the internal combustion engine. It's night and day.
Let's not lose sight of the wood for the trees.
Motorway noise won't be reduced by electrification:
Graph: Car noise sources, ICE drivetrain with a notchy transmission.
The little table about cars and trucks compares the crossover speeds above which tyre noise surpasses drivetrain noise.
Meaning: The constant traffic roar in the suburbs will continue, because at dual carriageway speed, eliminating drivetrain noise has minuscule effect on total noise.
Urban planning won't be improved:
Heavy metal pollution will be reduced:

Microplastic pollution will increase:
I'm failing to see how the first image is relevant. Isnt that comparing cars and trucks, not electric and ICE?
