Tailpipe emissions are only half of it. The brake and tyre dust is the second half, and not solved by EVs.

Brake dust is at least mostly solved by EVs, because regenerative braking does the vast majority of the braking work, thus no dust. Tire dust is real, but is going to be there no matter what kind of powertrain a vehicle has. EVs have more wear, but it is marginal. A Tesla Model 3 weighs less than any new pickup truck for sale today.

I'm an EV fan but this is apples to oranges comparison. EV vehicles are substantially heavier than their ICE counterparts. Their instant torque also wears tread quicker. That's just facts and there's nothing wrong with that. The world is not black and white.

Tesla model 3 curb weight: "3,552 lbs to 4,072 lbs"

BMW 3 series curb weight: "3,536 lbs to 4,180 lbs"

This works the opposite of how you imagine it does. Because electric motors have a flat torque curve, electric cars typically use a single-speed transmission, e.g. Model 3 has a fixed gear ratio of ~9:1.

Modern ICE cars typically have around 6 gears and the lowest one will have a higher total gear ratio than that, more like 15:1, causing wheel torque to be around two thirds higher in that gear proportional to engine torque than it would be at 9:1, and the engine's torque peak is commonly ~2400 RPM, which translates to as little as 10-15 MPH in first gear.

Electric cars like the Model 3 Performance accelerate quickly because they have >500 horsepower. So do ICE cars with equivalent power. Meanwhile something like a Nissan Leaf has similar power and correspondingly a similar 0-60 time to a Honda Civic.

To put it another way, there are very few modern cars where you can't hit the traction limit of the tires by putting your foot down in low gear, so the limit was never the powertrain to begin with.

Electric cars typically have a faster 60-100 time than similar ICE cars, because then the ICE car has to use a higher gear, but now we're back to the thing where this is hardly relevant unless you're accelerating the vehicle flat out to 100 MPH.

Brake dust is significantly less. Modern EV specific tyres paired with moderated torque curves significantly mitigates the tyre dust.

Fossil fueled vehicles are still significantly worse for the environment and health (before you even start considering the wars and bloodshed for the fossil fuels that we're currently witnessing in Ukraine and Iran). Don't accept the propaganda.

More like 99% of it. But either way, perfect is the enemy of good.

My 13 Chevy Volt has 225k miles and is still on its original brake pads and rotors. The rotors are basically good as new, and the pads are at about 40-50%.

But you agree that if we can eliminate half of the problem, then we should do it, right?

If driven smoothly, EVs solve most of the brake dust problem.

I have nearly 125k on a M3P, on the original pads. Right foot tends to be heavy on both pedals. Regen takes a lot of the load, makes a huge difference in pad usage / life.

Exactly. And EVs are marginally heavier if tire dust is an actual concern. Massive SUVs and pickup trucks should be criticized first.

They sadly also increase the tire problem significantly
