Fundamentally you can't really out engineer yourself out of the fact that using about 2 tons of metal to drive an average of 1,2 passengers somewhere is just inefficient

also still has the same rubber pollution from tyres breaking down as a combustion car
most bicycles also have the tyre problem, but obviously significantly less as the tyres are smaller and experience less wear

EVs have worse rubber and brake pad pollution because they are a lot heavier. Some of that might be, theoretically, offset by regenerative braking but that is trusting multiple million people to not drive their car like fast & the furious brained dicks.

Anyhow, your average marathon schwalbe puncture superproof, among the heaviest tyres, weighs about 750g a pop, so 1,5kg for a bicycle. Your average car tyre weighs about 8kg. If we assume you ride both of them just into the fucking ground, like near rim on asphalt type situations, you can do this 21 times over for a whole bicycle before you get one car of tyre wear.

good point, i forgot about the weight difference

yep, even at the extreme less tyre means less broken down rubber to fuck up the environment

That's only if you don't burn rubber on your bicycle. Put the trucks and sports cars to shame with your 2 calfpower speedster.

There are non oil bike wheels made of natural rubber. Haven't tried them yet

It is worse than that. They use some rare earth minerals too and thus, they release around 50 tons of carbon dioxide per car compared to 20-30 tons of carbon dioxide per combustion car

bollocks to that, EV cars are enviromentally better. Sure, there's problems there politically as per the idiotic plans to junk 8 gajillion ICE cars and replace them with new ones and such, but the concept is sound in the sense that it's the least worst car. It's just that least worst car is still pretty bad considering how they're used and the whole endeavour about the EV car revolution is not about saving the planet, it's about saving car sales

The upfront cost is higher but they win out over time and distance driven. They're still bad for all the reasons cars are bad but they're better then ice cars
