At this point is there anything about cars that doesn’t harm public health?
The big ones pacify the younger blue collar workers, can’t think too hard or protest if you’ve got payments to make on their super cars.
That doesn’t sound like a good thing, unless you accept the classist premise that blue collar workers being mad or protesting is bad.
Sometimes they kill members of the bourgeoisie
no
when you need to get to a hospital quickly
I feel like that’s not typically done in what you’d call a car in most of the world
That’s what ambulances are for. Which are a type of car to be fair.
I think about this daily
The new study reveals a problem that may grow as electric cars become more and more common over the next several decades. Electric cars, Smith explained, are not truly zero-emission vehicles, so municipalities need to think about strategies to reduce emissions from brake use as well as tailpipes
completely nonsensical. electric cars barely use mechanical brakes if you’re using them right. Hell, if you’re even a little efficient with your driving you shouldn’t have to brake much in a traditional car either (although it will always still be more than with electric regen).
tire wear is the issue for electric cars that isn’t necessarily strictly better than gas, and you solve that by hooking several of them together on metal rails with metal wheels or by having an appropriately sized capacity for 90% of your driving. this is, of course, impossible for americans.
You have to remember that american “evs” are all slated to weigh 6,000 pounds or over. They’re not like a Nissan leaf or anything. And manufacturers also tune the regen braking way down because Americans are babies and can’t figure out how to drive elastically with the pedal and regen on. This is to say, all the same problems with gas cars are essentially copied into evs.
Emissions over the lifetime of the vehicle normally from ICE are frontloaded to rare earth metal mining for enormous batteries and heavier weights generate more tire wear and require larger tires that are also more wasteful to manufacture. It’s a continuing example of the failures of individual auto based transport.

i’m not gonna stand up for cars as a primary solution for transit, but you kinda undermined yourself if this is your thesis since most of those issues are specific to american bullshit.

Well I’m sure it all being dependent on millions of individuals doing the right thing always will, despite all the proof to the contrary, work out this time
fortunately for this issue in particular, having regen settings “correct” by default from the factory seems to work everywhere except
i’d prefer trains or a
fifteenfive minute city because my knees aren’t going to get better, but if the best yankees can do is misconfigured EVs that’s still an improvement for local air quality and noise pollution.fortunately for this issue in particular, having regen settings “correct” by default from the factory seems to work everywhere except
That still doesn’t stop people from doing the quarter mile for every intersection, speaking from experience.
Mandatory engine braking is the solution. Everything will use regen brakes whether you like it or not
For somebody with a theoretical degree in automobile engineering, what’s this alternative to brake pad brakes?
Slow down by making the engine/motor spin. Shifting down makes the kinetic energy of the car drive the engine, rather than the other way around with the removeding forces of the engine slowing the vehicle. Large trucks with diesel engines are often equipped with a decompression brake or “Jake brake” so named after the first manufacturer of these systems, Jacobs. The big problem with engine braking on internal combustion engines is that it’s LOUD to the point where many areas restrict its use. You may have heard a kind of falling off farty rumble when somewhat near a highway. This is the Jake brake in use, and that sound can carry for many kilometers, hence the use restrictions.
In electric vehicles, you can use the motor as a generator to recharge the battery, slowing down the vehicle. This is silent and also extends the range of the vehicle so many EVs hardly ever use the actual brake calipers. Some but not all ebikes have this capability, but it should be mandatory imo.
Driving those Chinese “evs” that are like barely bigger than a golf cart (aka a vehicle suitable for 90% of the average person’s transportation needs) would use a sure of a hell of a lot less brakes.
ackshually with regenerative braking my 18 ton E-HMMV with the child pulverizer trim level is fine because we all know how people in cars always coast to a gentle, energy optimized stop
brakes used to be made of asbestos, now this
you’re telling brakes don’t just stop moving parts to slow down the car and instead produces chemicals
God that emoji is disturbing
mfw barely getting over the revelation about tire dust and microplatics
You mean to tell me there’s actually friction applied to materials on a large scale going on? And that brake pads don’t last forever but get worn down?
And with cars getting heavier and bigger, this is just going to get worse and worse.
