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:

As, Hg and Se exhaust emissions were dominated by fuel combustion while Cd, Cr, Cu, Ni, Pb, and Zn exhaust emissions were dominated by lubricant oil combustion.

Microplastic pollution will increase:

Are you some kind of source-posting diety? I submit myself for worship

I'm good at finding sources, not citing them properly.

I used to work at a university traffic research unit. I tried making a pedal-electric car but failed.

Luckily we have Podbike: (I like it, but the price)

They should invest more in design for manufacturability to improve quality-per-price ratio.

Cool! I do ride a custom ebike and always wanted a lie-down version for the aerodynamic advantage, but I honestly don't trust cars to notice such a low profile vehicle
