Good to have more data points and evidence, but this seems extremely well established by now? Zero tailpipe emissions, drastically removed brake dust, slightly higher tire wear (due to weight), but much better overall than ICE.

>drastically removed brake dust

It will be very interesting to see the data for the same car that has many powertrain versions for example the Lexus UX with the UX 200 (ICE), UX 300h (hybrid) and UX 300e (EV) to test which one the best and the worst in term of brake dust residue.

My hypotheses is that for brake dust residue the best is hybrid, 2nd will be ICE and the 3rd will be EV. This is due to the fact that the EV version has at least several hundreds kg extra weight (about 400 kg extra), that makes the brake dust residue comparable to ICE if not worst based on the approximately 30% extra vehicle weight for the battery. The hybrid however only has approximately 5% more weight or extra 80 kg different compared to the ICE version.

Ban the stop and go hell of rush hour. Cars rolling at freeway speed without stopping pollute way less than drivers stuck behind idiots who can't just go forward down the road at the speed limit.

The human suffering and ecological impact reduced if only there would be a focus on enforcing speed minimums...

We should obviously ban combustion engine cars, at least starting with cities. I can’t think of a single clearer win for air quality.

Wow. Well, I like that the people that think like this also probably live I places where you are actually driving a coal powered car. Like the clowns in Hawaii that have extra subsidies for EVs… their power comes directly from burning crude oil. I’m an automotive EE, and and the truth about EVs is in a rush to push them out the door, the media and politicians have set the tech back at least a decade by pretending it…

Well, most of us don't have a plan B if the Earth is wrecked by pollution, but I guess if you beg Musk hard enough, he might invite you to Mars.

We can either do drastic things now, or desperate things later.

And manual transmission cars kinda, though the energy is still wasted of course

Depends on how you drive. I never engine braked on my manual. Brakes are easy to replace. Clutches are not.

You need not burn your clutch to engine break.

remember, your regenerative braking comes at cost of tire life. If driving Tesla, you can reduce the regenerative breaking from Maximum setting to Medium. this will reduce regeneration and will increase the "breaking distance" when you just let go of accelerator pedal. but it will increase your tire life significantly. also make sure to buy the "commuter tire" models - tires with high mileage warranty (50k miles+) an…

Huh? What do you imagine is the tradeoff between regenerative braking and tire life? Are you suggesting that stopping the car with conventional iron brakes is somehow easier on the tires?

the level of regenerative braking directly impacts your accelerator pedal behavior.

by reducing regeneration, you will increase tire life by virtue of modifying your acceleration behavior. Its hard for me to explain, but I just suggest trying the medium regenerative setting and you will see it yourself.

You will feel it, because the most of the tire wear happens when car decelerates. On less regeneration your car will decelerate less and will wear out tires slower

> and have to throw 1-2 tyres in the bin. That's your choice. We jack the car, pull the wheel, extract the screws, and use a tyre plug kit. Howto repair tubeless tyres with plugs: https://www.youtube.com/watch?v=nCwWPlaghfs Tyres with inner tubes can also be repaired, that's slightly more involved.

depends where the puncture is. too close to the sidewall and you have to bin them. if they've already been plugged once and theu get another puncture its off to the bin.

> if they've already been plugged once and theu get another puncture its off to the bin.

Again, that's your personal choice.

We've got off road and on road tyres we still use with four to five tyre plugs in them that have lasted a few years since their last puncture.

I'm in non urban Australia and have cars actively used with > 500,000 km on the clock. We were raised to maintain gear; be it cars, trucks, aircraft, excavators, bob cats, etc.

Even if everyone drove optimally, every road is going to reach a capacity where its physically impossible to maintain a certain speed. It's similar to network congestion. Mandating that everyone drive faster won't solve anything.

Just normal driving, it wasn’t quite so bad on our previous car which was a Nissan Leaf (with 30kWh battery) but our current Kia Niro just has a lot bigger batter (64kWh) and it is a lot heavier I suppose, the tyres just don’t seem to last as long. I’m pretty sure I’m using summer tyres all year round (I live in the UK) this was recommended by the dealer

I have the Hyundai Kona, which I'm pretty sure is just their version of the Nero (same 64kWh battery at least). I'm on my original tires after 44k miles.

I also have a Kona and I had to replace mine at around 30k.

It isn't just slow or distracted drivers. It is congestion. It is too many cars, and the impossible task of making them all "go" at the same time.

What we need is fewer cars and better shared transportation.

Heck, we should replace ALL cars with busses, and then they could go super fast with all the other buses. Make 'em small, so it's maybe 20 people per bus. That's 20 cars off the road, right there.
