so are you wilfully ignoring the obvious fact that this depends on the actual weight of the vehicle, or are you just posting despite not knowing what you’re talking about?
There’s a very very easy solution to this: Make the cars smaller and lighter. There’s no reason to make cars with 400km of range, it’s utterly insane.
If we just change the default design of electric cars from “4 seats plus a huge trunk” to “2 dedicated seats plus 2 seats that can fold down”, then the weight issue is more than negated.
The weight issue is because electric cars have extremely heavy batteries (the motors aren’t light too) and need to be strong enough to prevent those batteries from physical deformation in the event of an accident to prevent a battery fire
For someone so combative you seem to have no idea what you’re talking about
And as a city dweller, I can tell you that electric cars are also noisy at low speed because of the fake engine noise they add. I live on the 7th floor and can hear some electric cars better than gas ones when my windows are open. Some sound like they are always honking at low volume.
Yes, they’re better and will help getting cleaner air, but there’s many other negative aspects to using cars that also can’t be dismissed just because they will be electric.
Tires are actually kind of an advanced technology and inventing an alternative that is less polluting but somehow equally durable and good at moving and stopping cars is not trivial
But yes we will need new tire material eventually or new technologies entirely like magnetic repulsion cars or whatnot
Gross weight ~10% of a typical electric car, so probably ~10% tyre dust too.
For bikeways. If the plastic surface were designed to yield in a crash, a pedestrian could be safer hit by this than by a bare biker on a bare metal bike.
Takes less space than a biker because a 4-wheeler can be steered more accurately than a naturally unstable bike needing wobble margins.
They are marginally better than internal combustion engines and that’s their only merit. If you’re gonna have a car, it should be electric.
But yeah, electric cars are not only creating micro plastic pollution from tire shedding, they are also heavier and thus require more energy to move, as well as create more potholes.
Plus, they still require parking lots that worsens flooding and creates heat islands.
Worldwide, cars are also killing billions of animals every year, as well as around 2 million humans. Every 30 seconds someone dies injured by a car.
they are also heavier and thus require more energy to move
No, electric motors are a lot more efficient, 90%+. Internal combustion are at 30% something. So EV, while about 10% heavier, are much more energy efficient. They just carry less energy.
Any more info on that? I found this but it’s coming from an EV enthusiast site and I’d like other sources.
If true I’ll have to retire this argument and focus only on the other half a dozen issues with cars, like using energy to move a multi ton vehicle and park it everywhere a few billion humans go.

Electric cars also cause significantly more tire degradation which is one of the most significant sources of airborne microplastics

But air quality in towns with electric cars have cleaner air, whcih could reduce cancer
Yes, cleaner air is a positive aspect and it’s not insignifiant.
But cars also increase sedentarity causing higher cardiovascular disease and obesity risk for its users.
Electric cars also emit as much noise as internal combustion engines when on freeways, causing health and stress issues for poor people living near them in major cities.

Yeah air quality mostly increases but what doesn’t increase and actually gets worse are microplastics
We don’t measure microplastics when sources talk about air quality and pollution
So solution is… make tyres out of new materials

Not really simple or easy
Tires are actually kind of an advanced technology and inventing an alternative that is less polluting but somehow equally durable and good at moving and stopping cars is not trivial

lightweight low speed small electric cars in cities are an absolute win
heavy high speed (= more tire wear) electric cars is just more consumerist slop
Full-size cars, yes, but I wish we the people now stopped the fossil-lobbied lawfare against microcars.
Renault Twizy, top speed 80km/h
Kyburz Plus, top speed 30km/h
Less healthy than a bicyclist though, but better than a car.
Yes and tire dust already makes up 78% of the microplastics in the ocean.

Making them electric will barely change anything.
No, electric motors are a lot more efficient, 90%+. Internal combustion are at 30% something. So EV, while about 10% heavier, are much more energy efficient. They just carry less energy.

Doing the math, an electric car uses 15 to 20 kWh/100 km.
Gasoline car uses about 7 liter/100 km. That’s about 68 kWh.
That seems pretty straightforward with real-world numbers.
Renault Clio I -> 900 kg
Renault Clio VI -> 1200 kg
Both gasoline.
But now the same weight increase is a problem, right?
Yes. Fuck cars. Electric or not.
