Indeed, to replace a brake you must remove it first; and better brake pads there are. Oerlikon of Switzerland has brake pad technology that has near zero emissions and does not need replacing. It’s not in production due to pressure for revenue from service shops.

You're likely referring to DiscCover [1], a relatively recent development - at least Volvo Trucks has an agreement to use that technology [2].

The problem is that the car industry is notorious for long product development cycles. New inventions (unless you're Tesla, obviously) tend to take many years before they go from after-market / high performance tuning shops to mainstream models. It's not as bad as in aeronautics (if you want examples, look at GA still using leaded fuel and engine/airframe designs from the 70s or earlier), but still, there's no need to suggest conspiracies.

We can't save the planet or ourselves because it's not profitable.

Selling brake pads that don't wear out would be immensely profitable. Things people want get bought.

I drive an EV for over a year, I barely use the break any more. Single pedal driving is wonderful

Curious: How do you roll towards a red traffic light, do you somehow push a "neutral" button?

Just take the foot off the accelerator gradually.

The kia I drive still roll at a couple of km/h when accelerator is fully released and will not hit 0 unless you use a paddle by the steering wheel (or use the breaks).

You just slowly let off the pedal as you approach.

Something about this story doesn't add up. Service shops aren't even vaguely a cartel, if Bob's Brakes won't install the magic brake pads which never wear out, then Alan's Excellent Brakes shop will. If, on the other hand, a company has a vaporware product, that's a great excuse to offer the public.

I explained a bit more in a sister comment. The stuff ain't vaporware and Oerlikon no vaporware producer either - they're in the brake business for many, many decades, with a rich history especially in train brakes.

Electric vehicles are heavier, which means they must spend more brake pads to stop. But they also use regenerative breaking, which reduces pad wear. So I'm not sure if they make it worse or not.

But you rarely have to brake an EV though. I’ve had two EV’s over the last 6 years, and I have to remember to occasionally hit the brakes to keep them from rusting. One pedal driving is just money - saves power and is just much smoother over all than old school breaking. IMO.

I've never driven an EV. How do you approach stop signs and red lights other than braking? Is "engine braking" (regenerative braking?) strong enough to handle that big a fraction of slowing down in city traffic?

We need to go back to horseback riding. It's inevitable.

I suspect horses come with their own health issues. Can you imagine a city parking garage for horses?

I'd take a stable over a parking garage any day.

But yeah, the excrement does accumulate.

Tire wear and tear, which can also give off nasty particles, is also increased with the generally increased weight of EVs
