Wondering if the air will actually be better for humans though. There’s a lot more particles being ripped from the roads with these heavier EVs, and road particles are quite toxic as far as I understand, so not great. But yeah, great to have clear skies.

Most EVs by number in Chinese cities are electric motorbikes and tricicles, much much lighter than an electric car

Are electric motorbikes and tricycles heavier than their gasoline-powered equivalents?

Likely, but damage to roads increases with the square power of vehicle weight per wheel, meaning that just by virtue of being half the weight per wheel than cars their impact on road degradation is negligible.

Oh, nice, I didn’t know that we have hard numbers on this. Cool, thank you.
